So the entire brake system was bad in my XJ and I decide to upgrade to a 96 booster and master cylinder since I've replaced the calipers and wheel cylinders, pads, shoes etc. I've run into two issues that I could use some help on.

Problem 1: 96 Master Cylinder, new from O'reillys, booster from junkyard. I cannot get a pedal at all. I've bench bled the MC, bled at the lines to the MC, and still nothing. Should I crack the bleeders on the WC's and Calipers and wait for fluid to flow since everything is new and then start bleeding the brakes once I have fluid at all four wheels?

Problem 2: My brake switch fits tight and sticks which leaves the brake lights on. Do I need to grind the booster rod down some more?

 

Just showing you what I did.........






Why you are not getting pedal.........without looking at your entire system.....who knows?


I vacuum bleed now.......then a final bleed of each wheel with a helper. Never had a problem getting pedal.

 

FWIW.............


I got braided flex lines off an Intrepid, flared the metering block end. Saved a lot of hassle and cost nothing.......I just threaded them into the PnP master and paid for it.

 

Thanks. Looks like I have some more grinding to do. Great idea on the brake lines.
