"Ask the dealer to pull the wheels and inspect everything...including the parking brake assemblies. It is not impossible to have a premature wear-out on the PB...there have been problems with that design."
Are you sure the PB is the same design in the 2007 GM 900's that it was for the prior generation of trucks (GM 800 series)?

On Sunday i put a waverunner in the water then went home. Noticed that my turn signal were flashing fast. Then Mon. night noticed that now had NO turn signals, no brake lights, no parking lights. Fixed the turn signals but can't figure out others. All fuses are fine, no relays to be found. WOuld it be the turn signal switch? Would the water have caused all the problems? Or was that just coincidence?

I have a 2003 Tahoe Lt 4x4, just had front and rear pads and rotors replaced, hoped this would give the pedal a better feel, to no avail. my wife feels like the truck is not going to stop on time. the garage installed semi metallic pads, would a different type have helped or am I going to have to live with it?

Have you tried bleeding your brake lines? If air accumulates in them the brakes will have a mushy feel.

You're just going to have to live with it. Common issue. Welcome to the world of early 21st century Chevy brakes. There is a fix. Unfortunately it involves buying a new / later model truck; one built after the problem(s) were corrected.

88 3/4 ton Suburban braking problem

Extremley hard braking is required to stop vehicle. All new brake parts (master cyl, slaves, calipers, pads, drums, fluid, etc.) replaced. Has been this way since purchased used. Serviced by prof. mechs. that can't figured it out. Every thing appears to be routed correctly. Has 2" lift. Mechs. thought it might be the rear proportioning, but does not appear to be that. Anyone have any experience with this?

Doesn't that sound like a power brake booster problem?

That is what we originally thought. Everything has been changed with the exception of the lines and proportioning valves (front and rear). Besides the boost is a helper and should be able to be overriden with hard braking but it is nearly impossible to lock up the brakes. Except on wet pavement. Several mechanics have been stumped. They have pressure tested the entire system at the cylinders and this is within specs. Tried different pads and shoes, everything. It calls for semi-metallic but tried a straight organic and this helps only slightly but wear excessively fast. I know the vehicle is heavy but you would think that the brakes would still lock up.  It is just frustrating. It is most likely a small oversight that is obvious no one is seeing it. I even thought the rubber flex lines might be swelling and not applying all the pressure but that also check out.
