Hello everyone, Looking for some help with the dual caliper setup in my 330i. Trying to get everything sorted out before the track next weekend, so any help is appreciated! Long story short, I installed a dual caliper setup in my car about a year ago, but I was never able to get it to work. I was able to bleed the system, but the handbrake never had enough force to lock up the rear wheels. Fast forward to now, and I am trying to get the setup working. I thought my original master was to larger (3/4"), so I switched to a smaller master (5/8"). The results were the same, I could bleed the system, the handbrake will get firm, but no lock up of the rear wheels. Pulling the handbrake barely even slows down the car at all. There is still some play in the handbrake before it gets firm at the beginning of the master stroke. I bleed the brakes manually, and with a harbor freight vacuum bleeder. I am using speed bleeders on the calipers If that is relevant. Outline of my setup: Garagistic weld on dual caliper brackets Stock 330i rear calipers Wilwood 5/8" master (260-2636) Chase bays lines and handbrake I am not sure where I should be looking next. Is the master sized appropriately for the calipers? could there still be air trapped in the lines? Would a slight misalignment of the weld on dual caliper bracket prevent the brakes from locking up? Again, any help is appreciated, clutch kicking is fun but I want my handbrake to work haha. I've attached a video showing the handbrake inside of the car, and of the calipers as the handbrake is being pulled if it is any help. Thanks!
