Brake Question

Post by CincyGXP »

98 SE, new brakes and rotors 22000 miles ago. Car stops fine, no pulsation. However, when going down the road, there is a screeching coming from both front wheels that goes away as soon as you hit the brake pedal. Any ideas?

Thanks

Do the pads again. They're gone for whatever reason. Check the caliper guide pins, they may be seized. New pins are $15 or so for both sides. The caliper cylinder may be stuck, too.

I'd recomend a visual inspection before you replace anything. And you can ususally just take out, clean, and regrease the guide pins.

you know what brand / grade pads you went with. or what the general price range was on them?

I've been told these cars had a problem with the piston in the caliper sticking after you push it back in when doing the pads, sticks open and wears the pad in no time. When I did the brakes on mine I had to replace one of the calipers cause the rubber boot was worn and it would most certainly stick open.

Either the pads are riding the wear indicator or if you had the brakes done chances are piss poor pads were used and have hard spotted.. I think you might be on the indicators.. Inspect them..

The caliper on the right side was sticking and caused the right pad to wear prematurely down to the wear indicator. Thanks for all the input.......

are you sure there is not an issue with the piston or the brake hose?

Sounds to me like Don is leaning in the same direction I am. As the black flex lines clamped to the struts age, they can cause the pistons to not fully retract. They're inexpensive and easy to change. You'll have to bleed again though.
