Having trouble with the wife's 01 TJ's brakes. Spongy pedal. System IS bled. All new shoes and pads and hardware. It almost seems as if the rear brakes aren't getting as much pressure as they need. Is there a proportioning valve on these vehicles? Might this be a common issue on the TJ?
Are the rear wheel cyclinders leaking any? I think there is a proportioning valve on it. I flush out all the old fluid also if you have not already.
It's better to be dead and cool than alive and uncool.
Nothing like a permanent reminder of a temporary feeling. I have a few.
4.0 auto, 8.8 rear with detroit locker, 4.10's and 33x 12.50's
Did you adjust the rear shoes correctly? If so, Jack up rear of jeep and set on jack stands, I like to spin the tires up to about 25 and apply the brakes. Look to see how quickly the rear tires stop.
Of all the jeeps I have owned and with the same issues you having its always been a bad MC not proving the correct amount of fluid to the rear. This is assuming no air in lines, lines are good(no swelling) and shoes are just slightly dragging, and there is fluid in the reservoir.
So, after rebleeding several times, and eventually replacing the master cylinder, the rear brakes are definitely not getting near enough pressure. With the jeep on blocks in gear, when I step on the brake it takes abnormal pedal to stop the rear tires. They then want to creep unless I keep the pedal pinned hard. The only other component in the system is the distribution block located under the m/c. Could this block also serve as a pressure regulator and is it adjustable?
Does anyone on this forum have any real technical knowledge or is it all just about big tires, lift kits and winches?
There are some VERY knowledgable people here, but remember its a weekend and your post has only been here for a day and a half. As much as I disagree with him on some issues, you may do well to send a PM to mrblaine. (may be mr.blaine) . He does know quite a bit about the TJ braking system and may be able to answer your questions.
Also, for what it's worth, asking questions in an insulting manner as quoted above is a sure fire way to guarantee no answers.
Well with the new m/c and the rear brakes adjusted almost too tight it's quite a bit better. I think I'll take the pressure front and rear and compare the two. Here's a shot of the new rig. Thanks again for all the input.
