i have a 98 civic coupe ex..

It started to do this a few months back but now its doing really bad.

Its only the front brakes that does it and usually it will only do it randomly

when your driving. Also wile trying to bleed both front calipers and rear drums

i found that the driver rear drum has no fluid going to it, i don't know if the

front brakes locking up has anything to do with it.

The only thing Ive done is bleed the brakes n master.

does anyone know what it could be?

i know for sure its not the calipers or slider pins because both of the calipers

are doing it at same time.

maybe the brake master?

do you have your brake booster check valve on backwards?
has the prop valve been taken off?
have you switched to GIECO?

Try to surge bleed to get something anything out of the rear. Connect a 3/16 vinyl hose to the bleeder to more clearly see if anything is coming out. just open the bleeder fully and pump the brakes somewhat vigorously to 'surge' bleed. Try not to bottom out the pedal.

You've got to get something out of the rear bleeder before moving on with life...

what is a brake booster check valve? n where is it?
no nothing has been removed or replace i think. ive had the car
for like 2 years n it had lots of back yard mechanic work done to it most of it got taken care of...and no have not switched to GIECO. =[

and im going to try to bleed that drum tomorrow,but Ive tried to bleed it kinda a bit like you said to press it to the floor but nothing.

no one thinks it might me the Brake master?

You definitely need to clear the brake lines. A clogged line can cause the brakes to lock up. If the problem persists after clearing the lines, then lubricate or replace the caliper pins or possibly replace the calipers.

nOOb answer. your check valve is either inline or is connected directly to your brake booster, via vacuum line. Guys you can quote me on this... Id check your master cylinder. Sounds like it needs replaced or rebuilt if you can still do this on a honda. like I said nOOb answer. Just trying to help a fellow honda guy out.

Flawed logic. It's not impossible to have two clogged or bad calipers or seized slide pins on both sides.

OK so i found out what it was..

master cylinder, replaced it 3 weeks back and haven't been sticking at all.
wile i was there i flushed the fluid and replaced brakes, they got so hot glazed up.

thanks for your help everyone
