Brake issues updated Looking for some advice on shoddy brakes.. Posted about it before but I've made some updates over time. Symptoms: Far pedal travel Need to pump to build decent pressure Far travel will engage brake light, pushing pedal to floor again will reset it Poor brake performance What I've done: New prop valve New brake fluid and brake bleed New prop valve New mc cap Any suggestions? Hell bent on not taking it to a place to fix it, but its become borderline dangerous, especially in rain. Hoping its not the master cylinder ( all junkyard cars here have rear drum, I have ws6). But we will see. Any tests to check if the mc is bad? Thanks! |
Re: Brake issues updated It more than likely is the master cylinder, but I'd change the brake hoses too, it will help a lot, as old worn out hoses deteriorate internally and can actually baloon causeing a spoungy peddal and uneven pressures on your front brakes. |
Re: Brake issues updated The brake hoses looked pretty well kempt when I bled them. Almost new. I will look a little deeper when this bad weather stops! Lol. Would a master cylinder from a rear drum bird work on mine? Also any manuals on replacing it? Never done one on my own |

Never done one on my own Changing it is pretty straight forward, a good bench bleed before installing it will save you a lot of bleeding; you will still need to do a regular brake bleed after the install. The bench bleed eliminates you pushing a LOT of air into the system and increasing the time it will take to get a good bleed of the system. Here are a couple of 'how too videos on the subject; get back with us if you run into trouble or have anymore questions. Bench bleeding a master cylinder........ Changing the Master Cylinder...... |
Re: Brake issues updated I appreciate that! That was a very helpful video. I couldn't find one for a thirdgen, glad you did! Looks pretty straight forward and easy. Looks a lot easier (and way cheaper than other vehicles). I plan on going to auto zone to check the part numbers tonight, and if they're the same, I'll probably order one from JC Whitney or summit. Junkyard ones are too gone and not worth doing the job twice if the new one breaks. I'll be sure to post back once I get it done and if it helps with braking performance! |
Re: Brake issues updated Rear drum brakes doesn't us the same MC as 4 wheel disc. Might looks the same, but it's not. |
Re: Brake issues updated Pinch off all the brake hoses, is the pedal high & firm. Release each one (at a time) till you find the one that causes the low pedal. |

Sounds good, looks like I'll hunt down a ws6 master cylinder... https://www.thirdgen.org/forums/susp...fferences.html JamesC |
Re: Brake issues updated Pretty interesting read, from what I can tell I have j65 brakes, not the better mc though. Which I guess is fine, I'm just looking to stop without pedal pumping and rear ending lol. As an update, new mc is in the garage and I'm getting it done today along with bleed. I was not able to test the brake hose hoses, they do look pretty new (clip is still shiny). Benefits of buying from a car guy. If it is still spongy after, well the wheels will already be off for more trouble shooting! Let's hope they put me through the windshield |
Re: Brake issues updated Got to it today, master cylinder made no change, but I got to looking and the rear pads were loose. I remember my e brake hasn't worked since I bought it. I rigged it up to tighten it and I adjusted the rear calipers, now it works like new! Anyone know where I can get the entire p brake assembly? No lever, but everything from the lever, back for four wheel disc |
