I have a 1986 GMC Vandura 1 ton box van that a few of you may remember me asking about a while back. My new trouble is that the right front brake gets hot and it starts to wobble after some city driving. Not a big deal under 35 MPH but if I leave the city and hit the open road it wobbles like crazy for a few miles due to the heat the caliper is causing. I replaced the master C. about a year ago and the problem started and is getting worse after about the first 3-4 months. Today it was crazy bad and I need to fix it. Do I need to bleed that caliper on that wheel or what should I do? I thought maybe a brake line may be soft but I am not sure. When I step on the brakes it pulls to the left, after they get hot it pulls to the right while driving. the right is the main concearn. Thanks.
