I am working on a buddies commanche. the factory axles were shot.
We set a pair of new axles under it. using the d30 front and rear 8.25 from a 2000 xj. the axles swap is simple and easy. A little grinding flip the spring pads on the rear and we are done.
I removed the vacuum lines from the t-case and sealed the inputs. I also removed the vacuum line that fed the system in the engine compartment and sealed the source. As far as I can tell the entire vacuum system for the 4x4 has been removed.
I did not drive this thing in 4x4 prior to the swap.
the mj arrived in the shop as a daily driver, no cap on the brake master cylinder. yeah yeah I know. The rear cylinder reservoir was completely empty. the rear brakes useless and non functional.
When the rig is placed in 4x4 the rear brakes lock up after about 1/4 mile?
When in 4x2 the rig is perfect.
The only thing I can think of is a vacuum is sucking down the rear brakes. E brake and all work fine. Did I miss something in the 4x4 system or is it possible that the master cylinder is bad due to the dryer reservoir?
If it is the master cylinder why doe it do it only in only in 4x4?
