I'll try to sum it up quickly..
Bought 01 GM with 72K that had been sitting for about 4 years.....
Brake pedal was nice and high and firm but car pulled to right..
Had repair shop that repaired the vehicles at my job work on stuck brakes.
Pulled calipers off and left the lines open and hanging for a couple of days.
Got vehicle back and vehicle now pulled to the left (slightly)
Sent back and they changed passenger side caliper, got it back and brakes still pull to left.
Sent back 2 more times and they couldn't get it right. (didn't pay for this)
Figured I'd live with it till I got REALLY sick of it.
Following year, I bled the brakes (3 times, all the way around), installed new pads and found out that rear calipers don't match. RH side has 1" piston, LH side has 1 3/4" piston.
Recently, swapped vehicles with my girlfriend because it was having many safety issues that needed fixing.
Got my car back and realized that I can't deal with this any longer.
Read some tech data on this subject and evidently the HCU needs bleeding.
Anybody got any ideas besides taking it to someone who'll rape my wallet for 30 minutes of work?
Contacted a couple of Ford / Mercury dealerships and they wanna start off by charging me for diagnostics.
Even AFTER telling them how this all came to pass...........
Contacted the parts departments at these dealerships to BUY the electronic tool to activate the ABS so I may bleed it, got ALL KINDS of stories but couldn't buy it...
BTW, I have that matching rear caliper in my hand now.....
