...... At this point I think it's something up stream from individual brake locations as I have had problems with all 4. The funny thing (not really funny) is that normally its front left but has also been all brakes at one time or another. Never all at once but just one or maybe like this time both front brakes. Typically it is one brake not releasing at a time though.
......based on whats occurring with the brakes its definitely not a individual brake issue. I see no way this is possible considering it has happened to all four at different times. Never more than two at once but normally one at a time. Today it happened to be both front brakes. Based on this I feel its something either with the ABS system, master cylinder etc as the issue has to be more up stream of the actual brakes themselves. I'm no expert but I will be surprised if this isn't the case.
I can get a list for everyone as I have all that data. Again just can't understand how it can be a individual brake issue. Yes if one or two doesn't release at times I can see a binding issue, rust, needing grease or cleaning etc but starting from being a new truck, all repaired and cleaned multiple times and occurring systematically over a 8 year period just doesn't add up to me. I will see what I can put together next week for everyone. Thank you
From your postings on all the different forums it appears your looking for suggestions so you can hand them to the service advisor for the mechanic to look for. That will be insulting to most of the guys in the bay's and depending on the personality of who gets this jackpot it could get expensive.
Since your not the one doing the work the best suggestion I have would be to talk to people locally to find who would take the time to fully go over the system objectively once the 20mile problem is resolved.
As I stated earlier you mention changing rotors often. These will not cause the issue and only be suffering damage from the issue. You've changed pads numberious times. Those may or may not be part of the issue, but you don't state if they have been aftermarket or what brands, or if during disassembly there was any hangup. No where has it been mentioned if any calipers were changed, which could be more problematic then the other parts you've mentioned changing.
I've already stated where I would first look since this recent problem occurred within 20 miles of the install. Every time you have an issue it has to be looked at as a new problem. Could the stoplight switch be hanging up, yes but that typically causes 4 wheel hangup. Was the switch recently changed?
Did you ask the shop to just change the pads and rotors or were they aware to look for any other issues? The other question I would ask the installer is how they protected the front caliper hoses from damage during the install. But if this would be coming into my hands as I stated earlier I would duplicate the problem and check for residual brake fluid pressure first, but my more direct investigation would be pad fitment.
