My 2004 Grand Prix GTP Comp G has a
rear brake problem. I started to hear a scraping sound from the left
rear ( drivers side) wheel and looking at the rim I see a lot of
brake dust on it Also, recently I noticed that my e-brake pedal will
not depress when stepped on, stays in the up position and will not
budge. I took the wheels off both sides in the back and see that the
inner pad on the left side is shot. When I use a screwdriver to move
the e-brake lever on the caliper, I can move it to the engaged
position but when I remove the screwdriver pressure the tab does not
spring back... I have to push it back. But that's the case on both
sides, left and right, and the right side does not seem to have a
scraping issue. Here's my questions …...
1. How do I determine if it is the caliper that is stuck or a rusted/ stuck e-brake cable at the wheel ?
2. These calipers are the new type with the built in e-brake... I don't like these ….. how hard is it to get the e-brake cable off of them and back on.
3. How do you turn these pistons back in, assuming I don't have to replace the caliper.. since these are expensive??
4. If I have to replace the two e-brake cables going to the wheels, how hard is it to get that back together and adjusted ?
Thanks for any pointers..... I am trying to avoid bringing the car to a shop.. but I am stumped on how
to decide if I need to replace the caliper or the cables or both …. Thanks..
