Okay, I just recently swapped the whole GSR disc conversion (front&rears), new pads, new brake hose, new master (15/16), and a used 40/40 proportioning valve and GSR booster (290V). I'm having a wired problem, when I'm driving the car it brakes fine, but after awhile the brakes lockup? after it cools down its fine. My question is, is this a possible cause of a bad booster? Like I think the booster rod is getting stuck or something. Also it has a vacuum leak (where the master bolt's to the booster) is this a problem?. Has anyone have this problem? Also can't I just swap over the DX stock booster and used the 15/16 master? Please help me, Thanks.

remember all gsr came with abs.
possibly a plugged brake line

So what are you tryna say? bump

The vacuum hose that goes from the intake to the brake booster is backwards...yes it matters what way the valve thingy in the middle is facing.. go to www.kenskustomchassis.com and order a boosterless mastercylinder..i did. its real nice...and clean

Well I doubt it's backwards cuz I didn't even touch it when I installed the booster beside the one going to the booster. I checked out the link, that boosterless master looks nice how much do they run for? I just picked another booster from the junkyard for 50 bucks so if that don't work I'll try the boosterless one. Again thanks fam.
