jason Posted October 25, 2014 Posted October 25, 2014 1986 4x4 companche. Changed both calipers on front and tjen bled them. Still no brakes unless u pump them up about 10 times. Then lose them again. Trying to gravity bleed them now but only one side will gravity bleed. Any help will be greatly appreciated. Thanks
Eagle Posted October 25, 2014 Posted October 25, 2014 Don't ignore the obvious -- did you put the calipers on the correct sides, so the bleeders are on top?
jason Posted October 25, 2014 Author Posted October 25, 2014 Yes. I had to go check but yea there on top.
Eagle Posted October 26, 2014 Posted October 26, 2014 I have never found gravity bleeding to be effective. Enlist the help of a friend and do it the old-fashioned way.
jason Posted October 26, 2014 Author Posted October 26, 2014 K i try it in the mornin and see what happens. Start from furthest away first aint it. Thank you. Let you no what happens tomorrow.
jason Posted October 26, 2014 Author Posted October 26, 2014 Welp another bottle of brake fluid down and still no brakes. Started with passenger side and worked it over. All kinds of fluid comn out but still no brakes. Gettin quite agravated. Put diffrrent calipers on that can off another front end just like it and done the same thing. Still no brakes.
Eagle Posted October 26, 2014 Posted October 26, 2014 Sounds like there may be a new master cylinder in your future.
jason Posted October 27, 2014 Author Posted October 27, 2014 Nothin. Put a new front end under it with a locker. And now no brakes unless u pump them up about 10 times then u loose them again
jason Posted October 27, 2014 Author Posted October 27, 2014 Yea eagle thanks for your input. Guess i gonna start checkin in on one. Figured id try the cheapest first.
big66440 Posted October 27, 2014 Posted October 27, 2014 Sounds like there may be a new master cylinder in your future. I agree. BTW I would really recommend speed bleeders you can find them in the dorman section at Autozone theyre worth every penny :thumbsup:
jason Posted October 27, 2014 Author Posted October 27, 2014 Kool. Havent never herd of them but will definatley check in on them
nitroxsteve Posted October 28, 2014 Posted October 28, 2014 What was wrong with the old brakes? Nothin. Put a new front end under it with a locker. And now no brakes unless u pump them up about 10 times then u loose them again Did you have the brake lines open for a period of time? I am wondering if the fluid completely drained from the master cylinder and it has air trapped. I would try removing the master Cylinder and bench bleeding it.
joester1908 Posted October 28, 2014 Posted October 28, 2014 Sounds like an issue with the master cylinder as long as you're sure the bleeders are on the top. how much fluid have you pumped through? Like said previously, there could be air trapped in the system. but it doesn't sound like it bleeding it multiple times..
metrictonner Posted October 30, 2014 Posted October 30, 2014 99 44/100 % of MJ brake problems are due to REAR brake problems. 99 44/100 % of brake fixers only work on the front brakes.
jason Posted October 31, 2014 Author Posted October 31, 2014 Yea i gonna try and do all one last time from right rear to the front
big66440 Posted October 31, 2014 Posted October 31, 2014 I would recommend pulling the master cylinder off the booster and bench bleeding it to eliminate it as a possibility nitroxsteve has a good point, I've had a similar issue on a brake job before and if you have air in the master cylinder you can bleed the system a million times and you will have a very very spongy pedal at best.
