Brake Problem

[william.r]

After driving about ten miles all four wheels will start to lock up, after it cools down they will work fine. Has anyone had this problem or knows what it could be?:cry:

Check you proportioning valve - I wish I knew more about this piece, but I don't. Ensure that the valve opens and closes properly. Consult the Helms for this.

one caliper wouldnt cause all four to lock up i dont believe. e-brake possible. best bet take it to autozone they do free diagnostics testing. do this to rule out abs system.

thanks for all the help, believe it or not it was the pedal hieth adjustment according a dealer tech with the missadjustment it causes the brakes to apply and while driving the brakes heat up really bad and create a hyrda-lock in the calipers I didn't believe it myself but adjusted the hieght and haven't had a problem yet
