Done the M50 conversion used a clio servo car has abs all calipers are free moving brakes lack power pedal feels normal but yiu need to seriously stand on it do do anything and even thrn there lame
Servo is working vacumes good abs kicks in on a dirt road
Bleeding both power and pedal comes out fine no restrictions in the lines
When pushing hard on the pedal pull back slightly the brakes stay on
This is when the car is stationary

Been bled multiple times

Spacer between servo and MC slightly too long, or pull rod needs shortening slightly?

You need to work out if this is a mechanical/hydo issue or an ABS issue, I would try disconnecting the ABS (remove the fuse?) and see if the symptoms are the same.

Figured out the problem... Front calipers were locked.... Not rusted or seized the rubber seal was not letting them slide
This was with 2 sets of calipers ... Come across a pair of 51mm front struts complete for nothing of a problem free car that had abs also and it fixed the problem
Never got to drive it with the clio/M50 with good brakes though as i sold that (too slow) have a S50 to go in now

Sounds like a combination of problems, did you retain the original E30 master cylinder?

Yep tried 3 of them then got a known working one from a car so i could rule that out
Even changed the ABS pump wasn't until i put the untouched calipers on that they worked
