Brakes don't Bite Options

[bkrantz]

As part of my rebuild I completely replaced the brake system:
calipers and rear pressure valve rebuilt by PMB
new ATE 19mm master cylinder
new hard and flex lines
new disks and Porterfield R4-S pads

I went through many (many!) episodes of bleeding, with different methods. The pedal feels very firm from the first push, and does not pump up. Rear clearance is set at .004". I went through the PMB bedding process, and have driven around a bit.

But the braking force seems weak. When I get on the brake pedal, I do not feel any "bite". Another 914 friend drove the car and also agrees.

Any suggestions?

Thanks All! Have not checked the pedal box, but will. Mostly using the top bleeders after knocking on the calipers with a hard plastic mallet. Every 3rd or 4th bleed I'll do the lowers too.
Had Texstars in with the first set of PMB calipers. They glazed over and treating them with some emery cloth helped. The best pedal feel I has was at that point. Then I noticed the problem with the plating and leaking and started all over again. But with Porterfields instead of the Texstars.
My plan at this point: push the pistons back in and out a few times, sand the pads, check the MC mounting point that I think is OK, check to see if the rotors are glazed, bleed again and drive. If it's still an anti lock brake system I'll order an ATE MC and lines to the reservoir.
Will be a weeks or two until I can get to all of this.
Lets' all go for a drive in whatever P car is ready to RUN!
