1991 sunbird - breaks?

Jbryan_31 27 April 2005 18:08:34
 I own a 1991 Pontiac Sunbird (4 cylinder, 2.0 liter, 4 door) and about
month ago the outer break pad on the front passenger side started rubbing
the rotor. I have replace struts, ball joint, rotor, tie-ends, break
pads, break calipers and have balanced and rotated the tires. All of this
work and the pad is still rubbing. Any suggestions?

 Do you mean the pad is dragging on the rotor and wearing down?

Is the rotor getting hot ? To the point you get burned if you touch it
to long.

Sounds like your caliper is not relesing pressure when you take your
foot off the brake pedal. Check to see that the slides on the caliper
are cleaned & well lubed. A deteriorated brake hose may also be
collapsing interally not allowing the brake to release. Especially if
the brake hoses are the original's. I just went through replacing my
hoses and all is well again.
My left front was actually smoking it got so hot.

 the outer pad is dragging so bad that it is completely gone in about 2
weeks, but the inner pad has little wear... the rotor has got so hot that
it worped the first one that installed... my first thought was that the
slide bolts were not releasing so that was the first thing that I replaced
(new caliper and slide bolts)... It didn't hit that maybe the brake hose
is collapsing... I was also told that it might be a bad lower control arm
bushing going bad... I will have to try replacing the break lines and see
if that is it.. thanks..!

 More than likely you have a collapsed flexible brake line. This is the
"rubber" hydraulic line which is attached to the caliper. Fluid can be
forced through by the extreme pressure exerted by the master cylinder,
but it will not bleed off because the inside of the hose is collapsed.
Very common on older cars, especially if the brake fluid is not changed
on a regular basis.
