Default Disc brake conversion

If I have all the parts and tools can I do the disc brake conversion on my 2001 XJ in less than 10hrs?? including prop valve change and bleeding the lines.

Yes, that should be plenty of time... I just did the conversion a couple weeks ago- night & day better braking, fyi- I didn't do the prop. Valve, & I don't plan on it..

A complete noob could do this in 4 hours,by themselve,with the correct tools.

You would need a helper to bleed the brakes.I installed the PV & only bled the rear brakes & all seems well.

While you are at it,I would highly recommend changing the axle seals & bearings.They are the ones on the very end where the brakes mount.

You will need to rent /borrow a removal tool from a parts store.Takes about 5 minutes per side to remove & you can use your old bearing to help make the new one flush in the housing.

Good luck.

PS-I'm not a vendor.But thanks for the bump.

Ok, thanks for everone input but I have a major problem.... I'm not pumping ant fluid when I try to bleed the brakes. Not even to the front brakes which were not messed with. I put a new master cylindar on and still nothing. I've tried 3 corners and nothing. This is starting to upset me some as this is simple hydraulics. Need some Major imput.....

Did you swap the prop valve? If so put the stock one back in and see if that fixes it.
