I replaced the pads and rotors without cracking the system, when I got in
to pump the brakes back up to tighten up the calipers the pedal just keeps
going to the floor. I tried bleeding the system, both grvity and regular
bleeding. Still going to the floor. I can pump them up with the engine off
and it feels like there is more brake pedal there but while holding them
down and starting the engine the pedal just stays put. Need answers quick
that's a tough one. the breaks should clamp down on the roter with no
problim. I guess I would check the roters for correct thickness. But
even if they were thin the calipers should work all the way down after
a few pumps. I think you have air in the system or your master cylender
chose this time to fail.
be extra sure you get the Exact right master cylender. when i changed
mine i ran into a plunger depth nightmare and bench bleading it can be
First mistake, on a 98 you cannot bleed the brakes without the proper
equipment, you need that little machine the dealer uses to do it, just
bleeding at the wheels and gravity bleeding wont work, trust me I have a 99
Jimmy and they are the same....anything with that big ugly ABS box underthe
hood you cant bleed the old fashion way
try turning the ign key on eng. not running then pressure bleed the brakes
with the key on and you will have better luck you should always open the
bleeders on anything with abs before you push the pistion back pushing
fluid back through a abs unit really upsets it
