I installed my BMW calipers along with new hard lines, stainless hoses, and porterfiled r4s pads. The car feels better now and I can lock up the front brakes.
So for my question: when I changed to the new calipers I can no longer use the locking plate for the caliper bolts for the BMW calipers (caliper is in the way). Little plate with tabs that you bend over to stop the bolts from coming out. So what should I use. Lock washer etc. any ideas. See pic below for plate. It goes on like a washer and you bend the little tabs hanging off the end over the edge of the bolt
Couple of things I found out. The brake shield needs to be bent slightly to fit the calipers. It is easier if you disconnect the old caliper and let it hang from the hose as fluid will keep coming out otherwise. Takes time to get the new lines set up and rebend the short hard line. A 6" line is all that is needed for the caliper to hose. (I bought 8", looks like a big S now). Speed bleaders rock. They worked just as advertised. well worth the 12 bucks for a pair. http://www.speedbleeder.com/ You just back the bleeder out 1/2 turn and pump the brakes. The bleeder has a one way ball bearing and spring inside that only lets air and fluid out. Once you are done pumping the brakes until no air comes out, just tighten the screw and you are done. Easy one person bleed job.
