Brake Housing & Cable Installation - Drop Bars

[@christinabenson5591]

I love the explanations of why each step is done how it is, I watched a couple other videos on the subject which were very hard to follow, but this was perfectly laid out. Thank you!!

[@KD-mm3li]

I love these educational videos. As a bike mecanic by total accident it's amazing how helpful these can be!

[@CoresMusic]

I was literally SO confused by this when I first watched… I thought, am I going crazy or are the brakes the wrong way round? I didn’t realise there are different laws for different countries. In the UK, the front brake is always on the right hand side. Partly because of historical bike design and partly because of which side of the road we ride on. Learnt something new there… Left-hand/front brake still seems weird to me though. Especially as I also ride motorcycles…

[@ramonhernandez4955]

The simplest and most professional video about the correct installation of the changes and brakes. Thank you! greetings from Mexico!

These are some of the best instructional videos I have found. So clear. Calvin- you da maaaan.

[@paraponziponzipo83]

Thanks for the video. I learned much from it, as I did for all of your videos so far. Thanks to you guys I have been able to flawlessly mount brake and shift cables many times on my hybrid and city bikes. But now I'm having some trouble mounting a compressionless housing. A few years back I got my first road bike, which now needs some new cables, so I decided to try out a compressionless brake cable kit for the first time. I started getting the length right as shown in the video - mostly using the old housing as a template - but due to the very high stiffness of the housing I can't for the life of me find a good length and routing. The housing is so stiff that it partly engages the brakes without touching the lever, bringing the pads closer to the rim. If I try to get it a bit shorter, then the handlebar won't be able to move freely and/or the housing will get too tight when I try pulling the brake lever, since dual-pivot calipers pull the housing a little bit when engaged. Do you have tips for compressionless housing? Has anyone here mounted this type of super stiff housing without impacting the calipers' or handlebar's movement?

[@RicGillespie]

I knew how to replace my cable but had no idea how to ask for the mushroom end, as opposed to the circular end, so, this video was still a big help. Thank you!

Absolutely amazing. You’ve thought of everything a noob like me should look for. Full disclaimer I’ve fitted a rear brake cable today and cut too short. I can turn my bike now…

[@robertsmithjr.5839]

These videos are just fantastic! They’re very informative and I have learned a lot from them!

[@jessesmith4541]

Notice he's using what's known as strapping tape to tape the housing against the bars. Ordinary tape like electrical tape will stretch. When you apply the brakes, the cable wants to straighten out with great force. This will in turn make the housing want to straighten out, especially at the tight curve where the flat part of the bars curves forward. Stretchy tape will stretch here and the housing can move away from the bars. Strapping tape is a lot like a flat piece of shift housing with strands of fiber running length wise, preventing it from stretching.

[@lisanemetz3415]

Thank you so much for this video. Would you recommend to always replace the housing when replacing cables? Or could you reuse the same housing multiple times? Thanks!

[@parktool]

Typically housing replacement is suggested at the same time. There are exceptions to that of course.

[@davesloan4848]

MUCH LOVE AND APPRECIATION TO YOU GUYS!! Thanks for your guidance to upgrade my SPECIALIZED "Langster" track bike for every element, except the saddle is still in good condition.. Also assisted me to correct my rear and front derailleurs on my 2nd bike my other love SPECIALIZED "Allez". I have learned A LOT of valuable information from you guys and your videos. Now I have all the proper tools and knowledge (from your videos), not necessary for the bike shop, unless absolutely required. ALTHOUGH....any ideas for the 2018 Allez, saddle post is not round (it is an OVAL shape), cannot twist, but it is seized. I've tried coca-cola, WD-40, heat/cool, pushing/pulling methods to loosen with no luck. Any other ideas? THANK YOU!!!

[@parktool]

Is there room for it to go down? If so you may be able to use a mallet or hammer to impact it down just a small bit to break the corrosion up. Then pull it out. It may require a new seatpost. But at this point thats going to be a much better option than leaving it in the bike as it will only get tougher to get out. Good luck!

[@manuelcalleja92]

[@eriwhere]

@@parktool It's two years later, do you have such video now? I plan to change all my cables and housing (shifters+ brakes) on my shimano 105 (rim brakes). I would love a video to help also with the shifting cables.

[@k1dicarus]

Beware when you buy shimano sets, there are 3 different quality ranges. I highly recommend to pay the extra 10 bucks and go mid. The cheapest are 4€ for the set but use a spiral cable. And no aluminium endcap and no small guiding ends on plastic endcaps. No coating whatsoever. The mid ones are 15€ a set and have the straight protective cables. Shimano calls this SUS. They come pre oiled and have protective caps and the metal end cap. OPTISCLICK and SIL TEC fall into this mid category. The high end ones are 30€ a pair. They are polymer coated instead of oiled.

Hello there, I have a suggestion, can you do a video on mechanical disk brake road bike brake wire measurements and installation please.

[@parktool]

Good suggestion. The concept is the same. Will put it on the list.

[@EdBordin]

Excellent guide! One minor thing - I have read that often it is not necessary or even detrimental to oil the housing with modern liners as they are pre-lubricated, is this true? The reasoning that the oil helps keep out water does make sense but I can also imagine excess oil gumming things up over time

[@parktool]

Pre-lubricated will be with a grease, and the lubricating part of grease is oil. If there is grease already inside the housing, oil would be meaningless.

[@barryw9473]

I have a 2021 Allez Elite with internally routed rear brake caliper that has a lot of friction when lever is pulled. When I disconnected cable I found the caliper and lever move smoothly and when connected I can hear cable rubbing housing inside top tube. Is there anything I can do to get rid of rubbing other than replacing rear cable and housing? Thanks.

[@gumonthepants]

Gosh I’m happy to be here.

[@kennethwise7108]

Calvin, great video. I am looking at doing this as a winter project for my brakes and shifters. Do you know what style cable housing comes with the Shimano kit's? Also what's a rule of thumb for longevity on these cables, coated vs uncoated? Thanks

Thanks Calvin, you solved my problem. You're awesome.

[@neuroglider64]

So housing endcaps or ferrules aren't needed (or even possible?) on the pieces of brake-cable housing that go into the brifter?

[@parktool]

Thats correct. There are some that do require them but those are outliers.

[@coltwinchester94]

Should I lubricate the shifter housing for a brand new shimano shifting cable with coating?

[@toddhoskins4196]

wondering that myself. the meger instructions say don't lube. what do i do with the shimano cable grease i bought?

[@parktool]

Shimano housing and others come with grease already installed in the housing when new. After some time of use you will want to lube the housing and cable with your cable grease.

On these levers there is no room for a ferrule on the end but you need one on some other brands.

I cut my new housing to match the old housing, thinking that would be a shortcut. Anyone know why it fits as terribly as if I'd cut it for a completely different bike? Like not even close, now I'm lost.

[@rgr80120]

Question...how far do you run the cable housing? Does it go all the way into the levers? Both brake cables and shifter cables

[@ricardotijerina886]

there is a stop inside the levers.

[@Horseinacorset]

Did he route the front brake cable to the left hand lever? Is that an alternative somewhere? In the U.K., the right shifter is always the front brake.

[@parktool]

We are a bit weird here in the states. Right is rear left is front. This has to do with hand signals and driving on the righthand side of the road.

[@Horseinacorset]

Park Tool Makes perfect sense I guess! Thank you for the reply!

[@SODWF]

Thanks again for the great video!

[@squibbledobble]

Question: How would you determine the length of the cable housing on mechanical disc brakes? Do you just use the old housing as a template? Thanks.

[@parktool]

You are looking for sweeping bends in the housing and the ability to turn the bars easily. Not too long, not too short. Goldilocks. This holds true for all cable and housing systems.

[@squibbledobble]

@@parktool Thank you so much!

[@leftyseel8658]

Quick help pls. Rear rim brake caliper does not return fully when sti lever is released. Do i need to just clean amd lube the brake cables and housing? And if i do, do i need to cut the cable at the crimp, or can i just loosen the pinch bolt?

[@parktool]

Cleaning and lubricating the cable along with the pivot points of the brake is a great place to start and is typically the cause of the caliper not returning fully

[@leftyseel8658]

@@parktool Thanks.

[@attybong]

what about those link housing system by jagwire? are they any good?

[@jessesmith4541]

There are positives and negatives. They can be noisy with the housing clanking against the frame and produce "clicky" sounds where individual links creak against each other.

[@arot77]

very nice :)

[@philhughes2917]

I notice you don't use an end cap on the lever end of the cable. Should you use one if there is enough room in the lever body for an end cap?

[@parktool]

+Phil Hughes Always use an end cap where they fit fully into the component. For most modern drop bar levers, the bodies do not accept housing with the end cap. The sizing at the body is reduced for only the housing to fit. -Calvin

+Park Tool Ok, thanks.

[@cjfetters]

Does it matter if you do the breaks or the shifter cables first

[@parktool]

Not, do either first.

[@heksogen4788]

@@parktool Does it matter if brake or shifter cables are over each other or vice versa?

[@georgeh-s2667]

So shift housing is not appropriate to be used on brake cables. But could you use brake housing with shift cables?? Anything wrong with that?

[@parktool]

Brake housing is a wound single cable wrapped around the liner. It is strong laterally, but it is also flexible. This means with index shifting, some of the push and the "click" is lost in the flex. It simply does not transfer the action at the shifter efficiency to the rear mechanism.

[@metubeglvz]

can i use silicone spray oil to lube the housing?

[@1trucxhondamov589]

100% Thanks!

[@joselarrarte6964]

I am not sure, do you use end caps for the lever or just for the caliper?

[@tomgray971]

9:24 "Whenever an end cap can be used, it should be used." Always use an end cap where it will fit fully into the component. However, most modern drop bar levers do not accept an end cap.

[@bobbyhempel1513]

The shift cables on my Sora shift/brake levers come out of the side instead of the back of the shifter. How should I route them in that case?

[@parktool]

The so called "katydid" style lever have shift housing looping inward from each side. You want just enough length so the housing leaves the lever in a straight line as it arcs back to the frame housing stop. Hold it by hand next to housing stop and test it by turning the bars 90-degrees away from the lever are testing. It should not tug where you are holding it.

[@thomasberg6547]

What is the housing linke if you have CANE CREEK CANTIS with that extra 90 degree cable? Until where does the housing go and is there a normal pull to the housing to to the tension?? (Which I suppose is not normal but who knows how you tapped your housing?)

[@parktool]

kzbin.info/www/bejne/fKepmqWXZ8l0hrs Have you checked out this video yet? It might get you in the zone. The length of the cable housing is determined by where the stop is located on your bike. Some stops are build into the stem, others into the fork and still others are hung from a headset spacer. The goal is to have a nice smooth actuation which means that you should not have tight bends or huge curves. You are looking for that golilocks setup.

I want to know does the shifter housing do the works with the brake housing ?

[@parktool]

If at all possible use brake housing for brakes and shift housing for shifters. You can use brake housing for shifters but it will result in vague shifting. Shift housing used for brakes is not a good idea and can lead to injury. The windings of the housing can blow out under the pressure and disable the brakes.

You are routing the cables incorrectly..the right front brake should be on the right ..this way the cable drops nearly to the cable adjuster without pointlessly crossing the front steerer.
