So I just got my car finally on the road. It's been a long journey, and this is my first 914, so if my question sounds "dumb" - just give me a new 914 driver break. All of the latest "old" cars I've owned (74 TR6, 74 BMW) all had brake boosters. The 914 has no "boost". I find the braking power to be really somewhat below what I expected. What was I expecting? Well, since I have no prior 914 driving experience I really don't know. I'm curious if my "newbie" experience is just that I'm not familiar with the lack of braking power, or if perhaps I may have some issue with my brakes? Rotors all new, pads in good condition, good pedal pressure, 19MM ATE MC from PMB. Any "road tests" I can do to give me some sort of clue if all is well in brake land? Thanks, Len |

Bed the pads and bed them again.
Even old pads will benefit from being bedded in. The real benefit from bedding is breaking in the seals on new calipers. New seals aggressively pull the pistons back giving you a soft pedal. The more you bed the pads, the higher the pedal gets. |

As of yet there hasn't been much difference. There are all new o-rings etc. in the calipers, new piston seals, etc. New rotors, just old - but good pads. That said, I'll re-bleed the system - maybe this weekend, and see where things go. |
