Right just put rs turbo breaks on all round. First of all will a 1.3 master cylinder be sufficient to power them?
And secondly they are biting but at a very low pedal point? Is this simply air in the system or a fooked servo, or is it the 1.3 master cylinder not being powerful enough?

Cheers

 

Try bleeding them see if that brings the pedal up i think the master cylinders are the same not 100% sure
