I just rebuilt my front calipers, including new pads. Have yet to re-fill/bleed.
On one side, the hub/rotor spins freely with only slight rubbing of the pads. Feels "normal" as compared to other cars I've worked on. On the opposite side, the hub/rotor does not spin freely. It spins only with some effort. Both rotors measure the same thickness (a little under 10mm). Will this issue fix itself once I re-fill & bleed or is something wrong? |

Should be a 20 minute fix if that's what you want to do.
Clamp the other piston. Blow this piston out. Inspect the knock-back shaft. Make sure it isn't bent as this can happen when using compressed air to get the pistons out. Clean and inspect the mechanism in the piston. You probably won't be able to get the assembly out because of the odd-ball clip so just spray and clean with brake cleaner and compressed air. You may want to let the piston sit with brake cleaner filling the cavity. This will helpd disolve some shellaced brake fluid. You should put some caliper grease on the shaft and reassemble. |

Already cleaned it out well before re-assembly. Assuming the shaft is bent, how to remove? I believe I read in an earlier post that the pin(s) were not necessary. As I mentioned previously, this is a temporary braking system (until I get my 911 stuff installed). |
