Would like your input on what could be causing the brakes to be VERY spongy on my
(Bought New) '03 GMC Sierra with 188,000. 5.3L 4x4. Not driven a lot anymore.
It has been spongy "before & after" the following maintenance:
* Rear ceramic pads, rotors, calipers & e-brake pads 1,000 miles ago.
* Amsoil DOT 3 Synthetic Brake Fluid 10,000 miles ago.
* Front ceramic brake pads & rotors 22,000 miles ago.
I even hear a "PSSHHhhhhhh" when I push them hard.
The only things I'm thinking is either the front Calipers, or I need to go "bed them in"
with 8-9 60MPH to 3-5MPH stops in a row.
I pull a 3,000 Lb Boat and it's slow to stop with just the truck, let alone having the Boat on.
Quite concerned about it not stopping safely.
Thanks!
