I bought drilled and slotted rotors with Ceramic pads on Ebay a month ago . When I hit the Brakes Hard the Rear Brakes will LOCK UP.That Sucks , I Have the Disk Brake Purpalsion Valve in and they still Lock up.

I guess you could try modding ZJ sensors to work. Again, just a guess.

2 or 3 months.

I have 2 kits right now & sending PMs to folks who are in line. If no response, I'm going to the next in line.
Once they they are fulfilled I will be offering them on a first come basis.

Did you bed the brakes?

PM sent.

I have one additional kit for a 8.25 but no lug studs. I'll knock off $25 from the price.

Both are sold & shipped.
I will post more when I get them.

Yes I bed them in like they said too. BASSLICKS . I am a BASSER too.

I zip tied my drum brake sensors in today . The ABS light went off,but came back on as I drove off . And the Brakes will still lock up when you hit them hard.

Right on.

I dunno man, that's weird. Might wanna try another prop valve then. Sounds like the one you have has a broken spring in it or something. Not supposed to do that, especially with a ZJ prop valve.
