Car has the following symptoms:
After I drive the car about 12 miles, the brakes slowly sieze up. The
longer I drive, the tighter they get and the harder the pedal
becomes. After the car cools off overnight, the pressure gets
relieved and the brakes loosen again. The front brakes are more
severely affected than the rear ones (you can tell by trying to spin
the wheels).
I replaced the front calipers to no avail. The brake hoses were ruled
out as the cause of the problem. The Chrysler dealer's mechanics
didn't feel that the master cylinder or the vacuum booster were
involved because the problem wouldn't come and go as it does.
The problem is closely connected with temperature because, one very
cold day, the brakes froze open. Could only apply them the next day
when it was warmer.
Could the ABS (anti-lock braking system) or TRAC (traction control
system) be the cause of the problem? How can they (or the master
cylinder or booster, for that matter) be tested?
Coincidentally, the car started losing engine oil at about the same
time the brake problem started. Probably no connection.
If anyone has any idea what is going on, please help! This could get
expensive....
