I have a 1968 schwinn panther with the bendix coaster break and what I'm dealing with is when. I peddle the rear hub makes a burp burp grinding noise. What could be causing that

[@leojohnladio9161]

It's 2022 and you still have one of the best videos about bike maintenance 💞

[@chrisshaw380]

Why would anybody make more videos like this? Rj already did it a decade ago!!

[@JAMaxeRestoration]

Someone a distance from me is asking if I can explain how to do a coaster brake so I've been watching for the best video on youtube to send them. This guy is messy and very awkward like a back yard mechanic, but he gets the job done. This video is 7 years old I'm sure he's gotten better. Anyone looking to learn how to service a coaster brake, even if you have a different brand, this video is still worth watching.

[@wanted-33]

I know this is an old video, but I've got to say thanks RJ. This is what I needed to see. Being retired I needed another hobby, and buying old bikes, servicing them, and giving them to kids in the neighborhood was what I chose. I've learned to service the crank, front spindle, and headset already. The rear hub I saved to last as I figured it would be a bit more technical. But, this video made it look easy. Also, the first thing I learned was "Grease is good" after doing my first crank. :)

[@abelaxen]

FINALLY a lucid vid on the topic. Thank you. This helped IMMENSELY!!!

[@SamDrayton-p3m]

I love seeing someone working on bikes.. i been working on bike since i was 4 years old. Now im 60..and still doing it..thank you for making this video.. i love bicycle s.. i all ways will till the day god calls me home..

[@robertengland8769]

Being a good mechanic myself, this is my sort of video. Fascinating how stuff works.

[@allenevonich3486]

Thanks, my neighbor bought a used bike that had the same problem. I followed your video and took the hub apart and cleaned and greased it and now it's working perfectly.

[@Defyboredom]

I have this exact set up on my old school schucks bike. This was incredibly helpful after I did not pay attention in disassembly 😅. Thank you for taking the time to record and upload this!

[@caralie2109]

Best coaster brake video on KZbin, hands down. Overhauling never seemed so possible! And your grip strength must be God Mode.

[@RJTheBikeGuy]

Grip strength? Not really.

[@corvette412]

thanks for the video...i just refurbished a 1972 schwinn breeze from my great aunt for my daughter to take to college...your video saved me money on rebuilding the Bendix 70!! cheers

[@brightcomet22]

RJ, i just got in a 1975 Schwinn Fair Lady stingray with this exact issue. the hub inside was full of ancient grease that dried up into a hard tar. cleaned up, all the Bendix parts were ok ...works perfectly again....your video saved this bike!

[@johnvanwinkle4351]

Brought back a lot of memories from my bicycle days….thank you!

[@jim_wilson]

Thanks for the thorough overhaul tutorial! I think I can go ahead and do this to my old beat up cruiser.

[@kimrice394]

Just watched the Bendix RB-2 and 70 videos. Fine videos! Got to thinking most kids now will never get to figure these out and get greasy doing it. I was driven as a child to figure these kinda things out. Get them properly grease and the perfect bearing pre-load for maximum speed! Simple designs but very consistent and the longevity!

[@tonipacheco7439]

Thank you so very much. This video was honestly the most help I’ve ever had with bike maintenance.

[@oscarfoxman785]

I’ve started fitting my BMX hubs with zerk fittings for easy greasing. Bearings last a lot longer, and it pushes dirt and moisture out.

[@timfoote2874]

I might be ready, lol.... I have been working on bicycles since I was 13, but I've been afraid to overhaul a rear hub, for all of these 50 years... thanks for the systematic explanation.

[@timfoote2874]

It looks like the hub that I'm looking to overhaul is a "New Departure". (1949 BF Goodrich 26" Bicycle)

[@michaeldower3041]

You may have just saved me from being ripped off $100 from the bike store. I am in the same position as you with a shabby bmx for free but I have the same running gear issues. A big thankyou to you

[@chrismackay8314]

Thanks so much for the great video. I'm piecing a bike together for my 3 yr old from a few that I found at the curb - basically working but were neglected.

[@jasonmorris1028]

Free bike.. Total cost bearing $12-15 and a $30 cone wrench. New wheel and coaster brake.. $40-50. I love how that coaster brake comes apart. Way more complicated then one would think. Nice overhaul!

[@WillMichaels-t8y]

Thanks I was working on this and doing poorly. Watched video and fixed it within 45 minutes.

[@dirtbikeboy66]

This video is not slow it is the perfect pace. Great video i finished the assembly about 30 seconds after he did.

[@andyben87]

Excellent! I have a Bendix 70 on a Schwinn hollywood that I need to grease up. This helps so much.

[@Maik1968]

Hello RJ, hope you have a nice Sunday! This video again was very helpful for my next projects: bought 6 old bikes on eBay and I will give them a second life for students living close to us, so that they are mobile and can get easier to the university. Take care and stay healthy 👍💪🌞🍀🚲

[@picorosita]

Hi, I've learned a ton watching your videos! I have a suggestion for setting the bearing preload on solid axles. I use a vice grip or a locked out nut on the bottom side while I tighten the cone nuts on the top, that way when you are tightening the top locknut the whole axle doesn't rotate. ;)

[@RJTheBikeGuy]

Yeah, I know that trick, but I guess I am lazy. LOL

[@Toto-is8ci]

@@RJTheBikeGuy I would NEVER call you lazy dude!!!

[@victorvillarongoarce674]

Thank you again RJ you have a winner overhaul! I was curious on how you fix a coaster hub and you show me how to fix and overhaul with your vedeo! Again thank you!Victor V from New Jersey

[@floyd6502]

I found this to be very informative for the bicycle project that I am currently working on. Thank you for sharing.

[@gelpi88]

I just got into messing with my own bikes and really enjoy your videos. Great explanations and detail. Thanks and keep it up!

[@jmundale]

awesome video. I ripped apart my old sears cruiser and scrambled the parts. I was able to reassemble without a hitch after watching your video.

[@jerryb1234]

Very informative video Bike Guy, I'm sure it will help many, many people, thanks for sharing.

[@katherinepoindexter4380]

this was awesome. I am taking apart a huffy's hub. I am learning about how to maintain bikes and this did help a lot

[@thefranconian6087]

Hi I'm also taking apart a 1980 Huffy Pro Thunder rear coaster brake hub and this is very similar and very helpful. Keep up the great videos. Thanks!

[@greenmachine55]

I definitely needed to see how you overhaul a coaster brake hub cause the cruiser bike I bought from someone used the turned in into a motorized bike with an 80cc/66cc bicycle motor kit and apparently rode it pretty hard and I have to overhaul the hub and decide weather I want to take off the entire motor kit clean it up and make it an ordinary beach cruiser bike again and possibly resell it once I get a different bike or clean it up rebuild the motor or get a new motor but upgrade the bike with a front brake

[@dougknoll5585]

Thanks for this super helpful video! I have rebuilt two Bendix coaster hubs with your help.

[@extorter]

rj thank u for this video, mine doesnt need to be overhauled yet but my sprocket did come loose and i was trying to figure what happened and it looks like that lock ring popped off. now i can fix it!

[@ESmithStringSlinger]

This video helped re-assembly of my '67 Coast King, Bendix hub. Works fine and thanks for posting!

Great video of the coaster brake operation

[@MrGreenvision]

Great video! Learned a lot today and tomorrow will work on my bike. Thank you for taking the time to post this video.

[@joshcolbert4682]

hey RJ i've watched this video maybe 5 times first time bike mechanic here and had a problem with a clicking noise in the hub, learned the inner basic mechanics of the inside, troubleshooted that the brake pads were obviously causing some friction, disasembled regerased still the clicking, and what it was was the Spring, the spring had been compacted during factory assembly i guess, so i opened it up and expanded the spring so the pads could fully disengage with the Driver, maybe this might help someone in the future, the spring wasn't disengaging from being too tight from the factory, i expanded with a pliers, packed with high temp grease and it's not clicking anymore.. yet thanks

[@jameswilson2815]

RJ, you continually amaze me. If you're ever in Hawaii, on Oahu, please ook me up. We'll tip a few on me. Aloha

[@skulledmonte84]

Thanks to this video I was able to fix my 76 bendix that is on a 78-79 Huffy with aluminum 5 spoke rims

[@agentseth5458]

Helps if you face the crescent wrenching proper direction as well. For torque purposes. Higher risk stripping your nuts when operating the cresent in the wrong direction as well

[@uptownphotography]

The coaster brake on our bike hub for some reason is engaging when you pedal forward. A half turn on the wheel when you pedal and it is locked. Yet, if you spin the wheel it will move freely. This started all of a sudden. At first the wheel seemed a little hard to pedal, but after about a 10 minute bike ride it now will not pedal forward because the brake is engaged apparently. Any ideas? Thanks and very well done video. Phil

[@klos1971]

this is great thank you my old cruiser has 4 brake pads not 2 other then that all went well

[@marof51]

And thank you for taking the time making this video and uploading.

[@e.stgo.7998]

Great video, keep it up, instructional and educational. 👍👍👍👍👍

[@johnwade5747]

The wear on the underside of the bearing race surface is indicative of too much end play ,probably from the same issue that made the stiffness of the spreader threads able to override the friction drag placed on the drag surface.Drag from the spring steel band should have let it thread in to brake and out to propel. HARD GREASE STAYS OUT WHERE IT DOES AS MUCH DAMAGE AS NO GREASE ON BRNGS. Very good video. I'm old, I like coaster brakes . Almost always fixable,usually no money!

Beautiful work

[@propabilityfpv303]

Holy crap how did you get that locknut holding the brake arm with your hand 😂 I ways need a hammer

[@jackduffy1817]

When you took it apart, I got the Idear that one or two parts had been put in back-wards, And when you reassembled, You did it correctly.

[@RJTheBikeGuy]

No, I think it was correct to begin with. Just all gunked up.

[@bullwhipjohnson8247]

I found the Bendix video obviously. It's good to know how those things actually worked after all these years.😉

[@captainprototype187]

I have just done this. I got it all to fit back after three tries. But now it doesnt turn as smoothly as it did. I can feel it kind of jerk sometimes when I spin it. It feels like a few ball bearings dont roll smootly. But this wasnt so before I disassembled it. Is it just a lack of grease? Im pretty sure I resassembled it right after the third try.

[@duncandee2514]

Crates if Pepsi and mountain dew is obviously powering RJ 😀

[@findmads]

One question. I Just took apart and serviced a coaster brake single speed hub. It takes half a turn before the wheel engages? What did I do wrong?

[@brandonkellogg9590]

Thank you. A question: why not just use high temp grease all around?

[@RJTheBikeGuy]

Because I temp grease is way thicker and heaver and stickier. And that is not what the instructions in the books say.

[@renearevalo21]

Great videos man!!! very detailed, very helpful

[@wiredworldwide]

Great video! This was very helpful.

[@hendy4584]

Maybe I haven't searched your channel well enough but curious if you have a vid showing how to convert from a coaster brake to a single speed freewheel?

[@RJTheBikeGuy]

Nope. Haven't done it. Easiest way would be to replace the wheel.

[@jimmcdowell6000]

Another very informative video. Thank You.

[@KenMuenster]

Thanks RJ for the overview of overruling a coaster brake. I used your video to aid me in rebuilding a SunTour rear coaster brake hub. I had great results with the rebuild, but when I put the bike on the road for a test ride, the coaster brake felt mushy and it took several feet for the bike to come to a complete stop. While in the rack, the brakes worked perfectly. Is there an adjustment I need to make to improve the stopping power of the coaster brake?

[@RJTheBikeGuy]

Does the brake engage with just a little bit of backpedal, or do you have to backpedal more to get it to engage. With a bit of use I am guessing the grease will distribute and it will work better.

[@KenMuenster]

Yes, as you back pedal, the brakes do engage, but the bike still takes a foot or two to come to a stop. I will keep checking the brakes to see if they improve. Thanks so much for your videos and your time!

[@murraydupley9330]

basically same question, weak brake force, do i need new shoes?

[@rishipictures]

What happens if you don't use a lot of grease? Dont you want it to spin nice and smooth? I have a royal enfield frame, I found the same 26inch wheels, I'm going to make a custom moped lol

[@lilvato88able]

Local bike shop wanted $15 to lube the rear hub saved money thanks

[@AK-ic1yj]

Is it possible to add spacers to the sprocket on a coaster brake hub for chainline adjustment?

[@singletona082]

RJ I have a quest ioN i'm prett ysure is a big negative. Is there a way to ahve a coaster brake and a traditional freewheel? I know of those coaster braike/kick shift hubs but I'm talking a more traditional. Basically my rear wheel taco'd, a direct replacement can be bought but i'm looking to see what other options exist since the bike is a sort of 'hey i got it to tinker with' thing.

[@_NyWrEj_]

Nice fix sir 😁👍👍👍

I have the same Bendix 70 and can't get to unscrew, must of sat too long. Have to figure out how to hold the clutch better somehow.

[@redpatrickdesepida8069]

[@MsRwilley]

i followed your video, all went well, i,m trying to get my bendix 70 coaster to work. my problem is it only brakes when i roll the bike in reverse. pedals forward fine, free wheels fine but no brake when i back pedal. got any ideas?

[@RJTheBikeGuy]

Not sure what went wrong. kzbin.info/www/bejne/gmPJYZhobamcqtE

[@daveallen2455]

I like to leave a little wiggle, when tightening the hub. Gives the bike its best coast possible.

[@hendy4584]

Good stuff. For all the BMX bikes I’ve worked on I’ve never worked on a coaster brake until I just picked one up. You mentioned using mineral spirits to clean parts, do you have an aversion to just using gas?

[@RJTheBikeGuy]

I don't use gasoline. I will sometimes use mineral spirits. Or often I will use dollar store degreaser and a scrub brush. Maybe followed by dish soap and hot water, and scrubbing.

[@zakdk1]

wow missed this one thanxs RJ !!

[@matthewabt9348]

i was riding my dads bike with a coaster brake and it started to make grinding noises when the brakes were applied. soon after this the hub started to have slipping problems both when pedaling and braking. after this the hub shell literally broke and spokes fell out. ever seen anything like this happen before? i've had problems with hubs in the past but never a catastrophic failure like this!

[@mechanknuckle]

Can you use white lithium grease on the hub and shoe area, or does it have to be high-temp grease?? Fixing my wife's 50 year old Schwinn cruiser bike.

[@RJTheBikeGuy]

You want high temp grease as those can get hot.

[@jcstevegigs]

Great video! I just did this to a rusty Huffy I found in the trash. First time for me. I just used regular lithium grease that I already had. And I reused all the bearings/parts after cleaning and the wire brush treatment. Question - It rides nice now with great braking but it makes a loud "clicking" noise when coasting unless I back the pedal off a bit. I understand what's happening and why I guess...is it normal? Is the mechanism worn beyond repair? Thanks in advance!

[@RJTheBikeGuy]

Not sure what the clicking is. Maybe somethings what worn out, or damaged. You should have used high temp grease in the drum. Here is a video showing how the brake works. kzbin.info/www/bejne/gmPJYZhobamcqtE

[@jcstevegigs]

RJ The Bike Guy the noise is the mechanism not fully disengaging. I can add the high temp grease pretty easy. Thanks. I just didn’t know if it should go totally quiet while coasting.

[@RJTheBikeGuy]

Coaster brakes general don't click.

[@topcat3149]

RJ The Bike Guy, do you recall where you found that diagram for Bendix hubs? Thanks! Getting ready to take a part another Bendix 70 and I like your video's for refreshing my memory.

[@RJTheBikeGuy]

This book: www.amazon.com/exec/obidos/ASIN/0517500930/ref=nosim/youtube25-20 It has a bunch of different hubs. Great book.

can you make a video showing how to remove a bendix or suntour coaster brake. converting it to a freewheel.

[@pedieasuncion6875]

I’ve disassembled the hub maybe a lil shy of 50 times and greased it and put it back together and it’s got a ticking sound idk why

[@pmd7914]

G'day, liked your vid. Do you know what is the purpose of the vertical up facing rear drop in at the very rear of the frame in your video? Could you please do one on a dept store kid's bike with a no brand coaster brake?

[@RJTheBikeGuy]

I don't know. Maybe something to install a rack. I generally don't work on kids bikes. And I especially avoid working on department store bikes.

[@MrRandyvan]

Yes, that drop-out was designed specifically for a Pletcher bicycle rack leg. If you google this rack, you'll see why.

[@ToddMorris]

I've done these before, but never greased the brake pads themselves. Did you notice any slip in the brakes from the pads being greased?

[@97warlock]

This was my main question too when watching this. Never heard of greasing the pads ....... Wouldnt wanna try that on a car haha

[@TBonerton]

This is metal on metal contact with potential for high temperatures. Grease must be used to prevent seizing up. Car brake pads are made of different materials, like ceramic.

[@97warlock]

The pads are glass smooth, Or close to it, the inner hub is also super smooth. There shouldnt be high enough temps to seize anything. The grease ...... will slide,causing longer time to properly stop. Or will require harder stopping power. .... This is really getting into the laws of physics.

[@SuperShecky]

@@97warlock Pads in a coaster brake experience pretty high pressures and temperatures. Remember, this is basically a tiny drum brake. Doesn't matter if they're mirror smooth, the friction , pressure and heat is quite extreme, as one might expect from a brake drum about 2 inches in diameter capable of stopping a 26 or 27 inch wheel with a 225 lb rider (ask how I determined this). Grease on the brake pads themselves not only don't hurt braking power, they keep the steel from losing the temper and seizing. Or squealing before that happens. Don't believe me? Try assembling a coaster brake hub without grease on the brake shoes and see how it functions. The squealing and abrupt performance will be a clue that there is not enough grease. Or just trust the old service manuals. If anything, I pack the inside of the hub with much more grease than shown. Has never caused any problem at all.

[@e.stgo.7998]

@@SuperShecky I totally agree with you. 🤔👍👍👍👍👍

[@dvdfrnzwbr]

Is the rear wheel suppose to spin freely like the front wheel? It looks like the way that you checked it gave resistance.

[@RJTheBikeGuy]

It's the fresh grease, especially the hi temp grease. It's thick and sticky. It will turn more freely after it is ridden a bit. But the action is smooth.

[@felixgutierrez8975]

Thank you mr. RJ but what was the problem i didn’t get what’s it please

[@derekhobbs1102]

They just get sticky internally, so 9/10 times it's just a clean and reassemble is all that's needed on coaster brakes

[@richardstumph7833]

Thank you, detail is key,, thank

[@97warlock]

Ive been working on an old Motomag rear wheel Bendix for many hours now. . I took it apart, cleaned every part with gas & toothbrush, let dry, wiped down with dry cloth, repacked with new grease & put back together, it doesnt roll good. It acts as if the bearing nut is too tight, like...give it a hard spin with your hand & it might go around 2.5 times maybe. I made sure everything is installed correcltly, 3 bearing cages are Balls down/Flat outward , axle straight, ................Makes no sense!! I backed nut off half turn so the axle has a slight play, still wont spin more than a few turns . Makes No sense!

[@pisto_run_cycling]

I have a newer style beach cruiser and I have a long travel in the pedal before it actually brakes.. and I dont get a skid when I stomp on the brakes like I should.. will a hub overhaul help

[@RJTheBikeGuy]
