Hey guys and gals. I have an 89MJ 4.0 5spd peugot STOCK 2wd
Recently I swapped out my stock master cyl/booster from a 2000 XJ, and made some new steel braided front whip lines for it. Well I did it at my house and then once I was all done and bled the brakes I realized the damn pedal is about a mile and a half too high!
So I took it over to my shop and it had the best brakes I have ever had on a stock vehicle in my life haha. Well I decided in order to lower the pedal I would take it all back apart and cut the Eyelet that the brake pedal bolt goes through from the booster and crop it. I measured my install length (to the center of the bolt) on both the stock booster and the 2000 booster. It showed that the 2000 booster moved the pedal 1.5" further towards the driver, so obviously that was the problem. The other problem I had was the the eyelets were different sizes and I couldn't re-assemble the brake pedal and brake light switch correctly as they had 2 different styles switches. I believe the first design was 1984-1990 and from there it changed to the design you see on most late models.
I cut the eyelet off the old booster and welded it to the new booster. Re assembled everything and now the height is exactly what it was stock. After dealing with minor brake fluid leaks from several areas I have an issue with the brake pedal being really spongy from when I originally put it all together. I have bled the brakes, but its still spongy. Also my "brake" light is illuminated on the dash. The only thing I can think of doing is driving for a few more days, hopefully it will let a little more air surface so I can re-bleed the system.
After all of that, is their any possible way I could have damaged that booster or cylinder when I pulled it apart? I did separate the cylinder from the booster when I welded everything and the booster was sitting inverted on a table so I could weld on it.
Any other ideas other than bleeding the system would be appreciated! thanks!
