Hello All, getting ready to do my rear drums and searching through old threads for any tips...... This one is seldom mentioned but worth repeating::
(Oldblueaccord mentioned a couple times I found)
When bleeding brakes, never push the pedal down more than an inch or two.
Instead of pushing the pedal near or to the floor, just pump them repeatedly and only push down about as far as your normal pedal movement to stop the car.... WHY? (unless you plan on replacing the master cylinder....)
After many years of use, the master cylinder will have a bit of crud coating the inside where the piston has never traveled. When you pump the pedal lower to the floor, the seals will wipe through this crud and when you are done it will soon be time to replace or rebuild your master cylinder!
If your brake pedal sinks slowly to the floor when stopped and applying pressure (and there are no external leaks in the brake system) it's likely the master cylinder seals leaking back into the reservoir.
I have seen this problem caused by pumping the pedal far too many times on many different types of cars and by trained mechanics who should know better too. Save yourself the trouble and expense next time you bleed the
OK, my contribution to the board today and thanks to everyone for all the great tips I have read here to keep my old cream puff beater on the road
