XJ rear disc conv=problem
I have a 91 XJ with no ABS. I aquired a 87 44 rear end with a disc conv. Being about the fourth owner I dont know the make of the conv. I'm guessing SSB. Any how I installed the rear end, plumbed the brakes and they're scary!!
The pedal is low and very front biased. I played with the proportioning valve and took out one o-ring to by-pass the restrictor on the rear side to allow a little more volume to the rear. This helped a little. I have installed a new oem master cyl. and bled them with a pressurized bleeder can. The system is air less after 1/2 gallon out each corner. I think the booster is good. The pedal goes down when you start it. I think I need a different master cyl. , with more volume,to the rear. Step on the brakes - stop slowly, mostly all front 2-3 pumps - better 4 pumps- great 5-6 pumps- getting rear biased pump it like crazy and the rear locks up I talked to the guys at SSB and they said they had a master cyl that might fix it for $160. I think there should be a good swap out there at a decent price, a parts store rebuild would be nice. A ZJ master cyl maybe What about mid 80's GM cars like the Firebird T/A with rear disc and no ABS? sorry I'm so long winded , thought I would spit it all out at once. Thanks in advance for any help.
