Hello, i have tried changing the rear pads on my s70 today, but only managed to change one pad on each side. I had the top off on the fluid resevoir, and everything was fine until it came to trying to push the inside cyclinder in. It would not budge, and was the same on both sides of the car. The outer cyclinder pushed in fine but the inner ones would not move at all....am i doind something wrong. The car was in park.....and the handbrake was off.

For starters the front and rear us disk pads and it is not hard to do. On the front jack up the front and us jack stand for safety. After you take of the wheel remove the two bolts at the back of the brake caliper remove the caliper and then the old pads us a C- clamp with one of the old pads installed in the caliper then just us the c-clamp to push the cylinder all the way in until it will go no further install new pads put back on. But before you do the next side hit the brake to push the cylinder back out. Go to other side do the same thing. On a side not you only need to replace the rear brakes every other time you do the front. The front wear twice as fast as they do most of the stopping.
could be a bad outer tie rod end or lower ball joint on the front suspension, to check jack up wheel (suspension supported) grasp tire and move back and forth, if you feel loosness you have a worn component. if there is no looseness then you have either an bad wheel bearing (excessive runnout) or defective rotors
did you replace All discs front and rear? if not , replace the ones that you previously didnt
The binding of the brakes is causing the pads to overheat, which is causing the smoke. You need pull the wheel and check things out. Your caliper must be bad (not releasing). You need to replace the caliper, brake pads, and have the rotor cut (a full service parts store or shop cuts the rotor perfectly smooth on both sides), or replaced (it may be cheaper to just buy a new rotor). You should also always change the pads (and check everything else) on the opposite side. So, if u do the brakes on the driver side front, always do the front pass. side at the same time, likewise if u do rear brakes. Whenever you do brakes u should also flush out the brake lines (by bleeding the brakes) until the brake fluid flows absolutely clear. Old brake fluid is the #1 reason for caliper failure. I've seen many times people replace brake components w/out changing the brake fluid, only to have the brakes wear out very quickly, or not function properly. good luck! hope this helps> please rate this!couontrycurt0
