Hello craig ,
sorry to disagree but ,definatley not the reason .The brake release dash light is very obviouse and right in front of you and this problem is very common.
My posting clearly states the exact cause .2 of the first trucks ,a suburban
and a 1500
pickup that I repaired were almost new with low miles ,this happens very quickly .Ive done at least 10 of these trucks in the last year
alone ,all the same problem ,why do you think the dealer says don't use it.
how dumb is that to tell a customer not to use the parking brake anyway?
Now, you mentioned you have a 2500 hd so that changes the story as it is
the 1/2 ton 1500
series trucks 6 lug wheels that have the trouble ,thats not to say others don't leave the brake on sometimes but ,definately the design.
remember i said GM redesigned the top retainer clip to try to keep the shoe
in the center of the spinning rotor.It has had some improvement ,no real
solution to the problem and there are many of these trucks needing repaired.
I will see more of them as well to repair .If I pull the rotors to check the shoe
only one side of the shoe (the side that has been rubbing leaning over onto
the rotor)will be ground down .even if the lining on the shoe was thicker
you still need to keep the shoe centered .If you get the chance to see
one of these setups being repaired you will see what I mean .There is no
maybe on this problem as to the cause .Gm stocks these park brake shoe
kits in large quantities ,and I have spoke to the local dealership owner here
in town when a customer was charge 80 dollars for a check on his 1500
and the rotor clips were never removed ,I pulled the rotors with the customer right there to see ,and the rotors were all tore up ,you can bet the dealer
service department got an earful .
