I have a 94 DX hatch i switched the stock front brakes for GSR discs and now the brakes are constently grabbing. It has brand new calipers.. ( second pair cuz i returned original ones thinking that was the problem ) brand new pads rotors brake lines booster master cyl. The brakes have been taken off and reinstalled twice and bled so many times but they keep grabbing.. I can drive my car til this is fixed anyone had this happen before? Anyone close to Fremont Ca that want to take a look... Ive read that i dont need to change the prop valve for this to work but I dont know..

By constantly grabbing, do you mean always locked, like a caliper is siezed? Is it both sides, or just one side?

Did you reuse the original brake hoses or did you use aftermarket ones?

What, exactly, did you swap? You only mentioned the discs, pads, calipers, but from what point does your 94 DX hatch turn into a GSR? Please don't say you only swapped the rotors... oh man... You need the knuckles too...

Check the Caliper Pistons to make sure they are perpendicular to the rotor surface. If not, then they are likely binding and wont press back in.

But if your Pistons are straight, and the Piston Boot is not bunching up oddly, then it is something else. Tell us more about what you changed for your swap (what came out, what went in)...

ok sorry I guess I was not very clear.. I basically changed the hole entire thing the hub and upper arm and everything. I also changed the master cyl the booster to match its al from 94 up integra non abs. I do know the calipers are not seized cuz it will work for a few mins when i first drive it... then they will grab and then not let go. Its not full on grab but enough to get really hot. My first thought was bad calipers with the gsrs so I replaced them with brand new calipers on both sides. Then the problem continued so I replaced those ones and problem still continues. Everything has been adjsuted and properly installed so im pretty confused as to what the problem could be. I guess ill have to triple check the pedal to make sure its fully releasing but its already been done twice....

did u change the prop. valve by any chance

psychoblue23

No I didnt. i was told by dealership mechanic that it did not need to be changed. Was he wrong?

did you just put the front gsr brakes on? or all of them? front and rears require the use of the prop valve from tha gsr or another non abs 4 wheel disc car. I dont know why its locking up but when i did mine, ive had no problems at all and its been like 4 years. Good luck

did you buy a new master cylinder? it may be old and worn out and binding.... the wheel bearings in you gsr hubs may be bad too, if theyre bad enough they might **** but i dobt that would cause it to stay locked up. thats all i got... good luck with it though, sucks havin a nice car and not bein able to drive it
