So, I gets a set of 320i brake calipers off a wrecked car the other day.
Very good clean condition, pads are like new. They were FREE, so what the heck right? I got a 70' so ..they bolt right on -- RIGHT? Not quite, but pretty slick. Bend the brake line, I had to grind on the outside of the actual caliper body just a smidge (through the part# stamping) because my wheels hit'm - 2 liter fuchs, totally stock. Not sure about that - anyways, Okay, bolt'em on, bleeed, bleed, bleed...adjusted the proportoning (big word) valve rod all the way in...tried IN and OUT not much diff. Pedal is still a bit soft, but works. Summary is: No Big deal, maybe I need the big Master cylinder? They work about as good as before. Pad area is like 40% larger, but it's not much of a difference- did I forget something? -Bob O |

There's not likely to be a night and day difference, esp. in gentle to moderate braking. You'll have to stand on it to notice much of anything, and it should be somewhat easier to lock up the fronts than it was before. Increased pad area will make no difference in feel or in braking power, just fade resistance and pad wear. Pad material can make a substantial difference to power and feel, however.
If you swapped the 17mm master cylinder for a 19mm unit, braking power would go DOWN for a given pedal force. The feel would change, with less pedal travel before things started happening, but you'd have to press substantially harder on the pedal before you got maximum braking. Some people like this, others think it just feels wooden and unresponsive. |
