So, I'm not loving the brake feel on the E30, and I can't for the life of me seem to improve it. Redid rotors, pads, guide pins, and SS flexible lines on all four corners and thoroughly bled the whole system. The brakes do work OK, but there is a significant amount of pedal travel before they really start to bite. It also doesn't feel like air in the lines, as that tends to give a more linear build up of pressure over a longer length of travel. This feels much more like mechanical 'slop' prior to engaging the hydraulic system. Anyway, I did some research and found recommendations to adjust the booster clevis length. I messed with that some today but to me it appears that all this does in move the pedal height around, but beyond that doesn't actually help take up any slack in the system. Am I missing something here, or is this just kind of the way the E30 brake pedal geometry is?
Hmm, slight update. Realized that after extending the booster clevis just a little (maybe a turn), all of a sudden the brake lights wouldn't turn off, as the pedal wasn't closing the switch. So I extended it a bit more (maybe another 4-5 turns) so that it properly rests up against the switch. So now the brake likes work properly again (although now I have no idea why they also worked before I touched anything), and the dead travel does indeed seem a bit improved, but now the brake pedal seems to sit stupidly high compared to the clutch and throttle pedals. What is normal for these cars?!? Is the brake light switch position adjustable independent of the pedal/booster adjustment?
