Hi guys. Newbie here...
1988 325i
Morther in law had this car and gave it to us, sat for a 2-3 yrs and knew it needed work but 0 rust. Drove it 150ish miles and the brake peddle left something to be desired. I ordered rotors and pads and then started to pull her apart.
The ball joints, tierods and front shocks were junk. Ordered replacement kit from FCPEuro. Full front end was rebuilt, I've done prbyy 20 cars brakes in my life. Took for a test drive and locked them up in my gravel driveway as a test. Then the peddle lost all stiffness and brakes were shit. Pull all 4 corners and attempted to bleed...
Rears would bleed with no issue. Fronts had barely any fluid even with the bleeder fully out. Read on here a few thing suspect master cylinder, abs or the rubber supply lines collapsed. Thought 100% possible on the lines as I propped calipers up during the work and they fell a couple times. Figured old hoses from 88 may have collapsed. I cut tepathe line and pushed the brakes and got a stream of fluid. Not super powerful but plenty of fluid coming out. Clamped it off and picked up new lines.
Installed both sides and on passengers side the caliper piston was fully extended and the inner oad was missing. Some idiot (me) for the forst time ever left a pad out as i found itbin my magnetic tray.
Try to bleed the fronts, still not much from bleeders. I pull bleeder fully out and still not much fluid either side. So what now? The reservoir has plenty of fluid, I can try power bleed tmrw. But do I target the master cylinder? How do I test it, how do I bleed the ABS pump? What issue may I have caused? Replace calipers?8
