My 88 XR3i has the MECHANICAL ABS and as its now all in peices i need some advice on the ABS bits, Can i leave the ABS front modulators off but still reatain the ABS MASTER CYLINDER. I realise that i can put the rear laden valves back on to act as the brake retarders for the rears. Also id like the ABS modulators testing...does anyone know of anybody that can do this? if anyone can offer any advice on this subject i would be very grateful as knowledge on this system eems to be limited
