mason Posted October 11, 2023 Share Posted October 11, 2023 Hi everyone, I have 91 warrior with 45'000 miles , My brake all of a sudden felt half way spongy after I had it for emission test in Jeffy loop. .I bled the rear tires and it felt good and solid but after a few days it becomes half spongy again. I plan to replace the master cylinder(85$) this weekend. I appreciate if anybody has a similar experience to share . Air gets into the rear brakes somehow..

Toycollector47 Posted October 12, 2023 Share Posted October 12, 2023 Rear brake adjustment? at least on the late 90s Chevy half tons if the rear brakes were loose it would produce a spongy pedal. past that, if no air in the lines then I’d look at a master cylinder.

Yes, I changed the master cylinder and the problem is gone. Thank goodness. Quote Link to comment Share on other sites More sharing options...
