I got a 95 teg rs MC, booster, and prop valve for my 93 hatch with GSR brakes all around. I installed them all, bled the brakes and found that the mc and booster were bad. btw, the gsr brakes all worked fine before these 3 parts

I replaced the MC and booster with new ones and adjusted the rod bolt on the pedal.

The same problem I had before happened again. The car started to drive fine, then gradually slowed as I drove it (less than 3 miles total), until the brakes were on completely. It seems to be only the front 2 brakes were stuck on.

I am pretty sure its not the prop valve bc it distributes power diagonally, so 2 front brakes locking shouldnt mean its bad.

I am going crazy trying to figure this out any info appreciated

 

I also read that a mismatched ABS booster and non ABS mc can cause problems, but I am 90% sure mine are both NON-ABS, is there any way to make sure?
