I hate to post such a stupid question, but I'm trying not to waste money.
(it's not my money to waste)
2002 Chevy Avalanche, 1/2 ton 4x4 dual piston calipers on all wheels.
Brakes have always been "squishy" but now the pads wore out.
BIL put all new pads and rotors on it.
Same day while testing the brakes, truck had not left the shop,
rusted out brake line to the right front wheel ruptured.
Replaced the line.
Now trying to bleed the brakes since the line was opened.
Got good pedal pressure engine off, solid fluid at the bleeders.
All four wheels.
With the truck running he's got air back in the lines.
LOTS of it. Right rear will sometimes bleed clear and the next
time blow mostly air. Not two or three tries, 40 or so!
Same symptoms keep repeating.
Go back to engine off, bleeds clear, good pedal.
Start the engine, pump the brakes, air in the lines again.
No fluid leaks anywhere.
Opinions? Bad master cylinder?
