hello,
I am currently upgrading my 914-6 to vented rotors. My hope was to take a Front "M" caliper and mount it on the rear using the 911 (69-83 Rear) vented rotors. I mock fitted the caliper and rotor and it looks like I need to place a small spacer between the caliper and the mount on the rear trailing arm (not a problem) The issue is the 911 rotors get larger as you get closer to the brake surface and rub on the "M" Calipers. Has anyone else had this issue? I realize they are larger for the parking brake, is there a parking brake delete option? 914-6GT vented rotors, suppliers? Thanks for any help, back to the drawing board! Steve |

what pads?
you can buy pads to run in different temp ranges when you bleed the fluid, is there obvious air? try upgrading the temp range of your rear pads go with cool carbon and select the next temp range up cool carbons, now called KFP's work great on sub 2000lb vehicles. Pagids are better on 2500lb+ cars, but not as great as the KFP's on the light weight vehicles. I go through rear pads at a 2 to 1 ratio compaired to my fronts. have you ever added cooling to your rears? It would be easy to do as a temporary test I finally modified my S calipers, by removing the knock-back pins to eliminate a little of the spongey feeling. are you running aluminum calipers up front or steel ones? b |
