How To Replace a Master Cylinder DIY

Netflix: are you stil watching? Someone's Daughter: 4:16

Cool video. I love it that you are helping that young lady learn how to work on her own car. I try to do the same with my daughter and grand daughters. Of course my grand daughters are 5 and 11 but they do try. Its nice when they can show the guys how to change a tire or check their oil.

If i don't have a vise, can I mount it to the booster and bleed it with a helper in the jeep? Then install the hard lines.

[@arizonanumbersstation1727]

Another great video Jerry. Whenever I need to work on my TJ I go to Bullshitkorner first.

[@owhatsthis4]

Dude....you're awesome! I have a 2003 TJ and I would not be able to understand what the heck I was doing if it wasn't for you. Thanks, beer's on me

[@metalhead4x448]

Would a faulty master cylinder make your rear brakes grab suddenly and then stick on? My rear axle is overheating cause the brakes are sticking all the rear hardware has been replaced.

That's one of the more informative master cylinder videos I've seen. Thanks! Neat to see Kerri likes doing her own work too!

[@BackCountryWrenching]

+UndergroundTrev she loves working on her own jeep, she's going to get me to weld in a new floor pan and perhaps look at her winch in the new future

[@UndergroundTrev]

Bullshitkorner Nice!

stripped bleeder screws are the WORST. how do I get the free play out of my pedal? my brakes are fine, but I have a quarter push until my pedal feels like it engages the cylinder, and I don't know how to fix it.

[@lauraguerrero373]

Hey buddy. love your videos and personality is best! Question? I have a 98 jeep Tj and the passenger side caliper locked up on me today where i just replaced everything less than two years ago for the same problem. Pulling to the right and smoking pads. What can be causing this? I changed both calipers, brake hoses, pads and rotors. Some say very dirty or contaminated fluid could be the cause. I looked at the fluid and it was dirty looking, just like the fluid you observed when you did the TJ caliper replacement. So my question is, can very dirty or contaminated brake fluid cause my symptoms? I didn't flush the fluid the last time. Just bleed it. Thanks bro!

If your jeep is a quipped with ABS you may need to hook up the computer to adjust the foot pedal. I had to to do this to my chevy truck I know they are different made model but may help. Hopefully this may help out.

[@thejakein7867]

Salvador Vazquez Jr these older jeeps dont have ABS

[@wyattoneable]

That's cool she was willing to get involved in the repair.

[@roccoliace7484]

Great video. Jerry you did an excellent job walking Kerri thru the process. Good to see a woman wrenching on her own Jeep!! Thanks for another money saving video! Give Tomcat an extra pinch of catnip for a job well done. MFBT

[@BackCountryWrenching]

+Rocco Liace She likes to do her own work

[@Teh-Jones]

I like this chick, good to hear there's more work on her Jeep coming up...

[@TrailRecon]

Excellent DIY video!

[@rhkips]

How much shit is in the brake lines? ALL the shit is in the brake lines! Great tutorial, Jerry! I always get nervous seeing "DIY" alongside anything to do with opening the hydraulic system, but you pretty much covered all the bases, so well done! At least your new master cylinder bled pretty easily! I've had a few I've fought for hours trying to get all the air out. :)

[@BackCountryWrenching]

+rhkips really that's crazy how did you manage to bleed them when they've been stubborn

[@rhkips]

Bullshitkorner Patience and creativity--the former of which I am definitely not known for. LOL Some master cylinders for vehicles equipped with ABS have really bizarre designs; integral proportioning valves, extra ports, differential chamber designs, etc. Pain in the ass!

[@BackCountryWrenching]

+rhkips I've never bled a ABS module, but I've noticed in my Matco Scanner for some vehicles it has a ABS bleed function. I would assume you'd set it up and the scanner would operate the module to bleed the system....... I've never done it so my guess could be all bullshit

[@rhkips]

Bullshitkorner If you've separated the master cylinder from the ABS unit, it's a good idea (often necessary) to run through a factory ABS bleed procedure, but you still have to bleed the master cylinder itself first. Some cars bleed the ABS unit by cycling the solenoid channels one at a time, others have a sort of "service position" that you place them into in order to bleed the system. Knowing the factory bleed procedure can be crucial. In some cases, if you don't have a factory-level scan tool, you can bleed the system manually, then activate the ABS by driving on a slick or loose surface, then bleed it again, and do that over and over and over until the pedal feels good enough. Definitely not recommended, but it can get'cha out of trouble if nothing else is available. :)

[@crazymanwithastick]

I've learned so much from you. Love your vids.

[@leesire]

I have a problem with my breaks on my 97 tj. Anyone want to hear my problem

[@ThePlowGuys]

Good Job Kerri. You can take over from that old man in the video with you. -John

[@morten8193]

Great video! It's so much more fun helping people when they are into it themselfe! I leave no comments on the repair, i'm afraid you become a verbal bully if i do, LOL One of my absolute favorite channel MFBT!!👍

[@rheidtech]

MFBT.....think my prop valve is buttplugged too. thx for the tip.

[@ManicMechanic007]

Rusted bleeder screws, fun city oh yeah.

[@BackCountryWrenching]

+ManicMechanic007 Your telling me, that's never a good time

[@SteveRobReviews]

I never knew there were roll punch punches , I always used a regular punch and screwed the odd one up . Ok I have to buy a set of them , isn't that pathetic LOL

[@BackCountryWrenching]

+STEVE ROB You learned something new today

[@UBBERTANKER]

+STEVE ROB i learnd about them when doing a crank pully on a hyundai which has a roll pin instead of a woodruff key so you take the pulley bolt off and try to wiggle it off but its stuck on the pin which is exposed so i tapped on it with a normal punch while puling out on the pulley and it just deformed and made matters worse lol ended up drillng it partially out

[@UndergroundTrev]

+STEVE ROB I didn't know those existed either. Not sure I deal with enough roll pins to make a set worth the investment though.

[@BackCountryWrenching]

what you mean 15 dollars off Amazon for a set

[@UndergroundTrev]

Bullshitkorner Well in that case....

[@scottnei]

Job well done Jerry

[@petersidnell2971]

how about a walk around the jeep

[@BackCountryWrenching]

+Peter Sidnell this jeep in the video is pure stock

[@petersidnell2971]

+Bullshitkorner I talking about your jeep so that we can see an update on it

[@ozzstars_cars]

good fix

[@klc317]

That was some gruesome brake fluid. Probably like driving a whole new vehicle now.

[@BackCountryWrenching]

+klc317 I suspected that the proportioning valve had quit working sometime ago because the rear disc brakes were all rusty

[@mizzteesmansion9241]

Lol loved this thank you so much!!!

[@547Rick]

Nice job!

[@vincentb123456]

mityvac them gravity takes to long for me lol
