Hello,I'm having a problem with the brake on my 240 volvo sedan w/ 205,000 miles on it.About 6 months ago my right front brake was overheating and the brake pedal was hard. I replaced the rotor, caliper,and master cylinder, and the problem was solved until about 3000 miles later when the left rear brake was overheating and brake lining was gone. However, the right rear pads was still thick. I replaced all four calipers and pads. Two thousand miles later, my left rear brake was overheating and the brake lining is gone, but the right rear is still thick. The only problem that I can think of at the moment is to replace the brake hose on the wheel that is overheating. Does anyone have this experience before and can you please tell me possible solution to my problem. Thank you so much and sorry for the long description.
