YJ Rear Disk Conversion
Hello everyone........I have a problem and I hope I get an answer. Since I had to rebuild the rear of my 87 YJ.......I decided to convert my rear to Disk and I purchased the Crown D35Disk-2 conversion and I installed it. I is not a direct bolt on conversion I had to drill new holes to the backing plate in order for them to fit. I installed the calipers and pads and when I went to install brake hoses the was no copper washers, I looked around the shop and found 4 and installed them. I bled the system and could not get the rear disk to work it seems that there was no pressure getting to the rear. In the instruction it states that on some vehicles you might have to install an after market adjustable proportioning valve and I did and there was no change. Thought that the original master cylinder was not adequate since I was for rear drum system so I purchased a Rough Trail HD Dual Diaphragm brake booster and high pressure master cylinder and installed it (I bench bled the master cylinder).......no luck I get no pressure to the rear calipers. I need help, any ideas? Thanks in advance.
