Topic: Disk brake upgrade question...

[TahoeYJ]

Here's a link to an 8.8 swap into an XJ, very detailed and should help (considering all 8.8's past ~96 were disk).

Thanks for that link. After reading his thoughts on how the brakes reacted with the pill removed, I feel that mine will be OK. Granted I'm still going to install a Wilwood prop. valve (A friend of mine will be in Reno in a week  and is making a stop at Summit Racing's warehouse, so I'm going to have him pick one up), but I think it'll be fine for now. I would think the XJ prop. valve is a bit different than the YJ valve, but probably pretty close to the same. I'll just have to drive it without the pill and see 

My main concern is towing... But by the time I tow anything, I'll for sure have an adjustable prop. valve in

Glad it eased your mind! It convinced me to choose to (later) install an 8.8! Looks like I may be job searching soon though, so such high hopes are unlikely...

I know what you mean. I wasn't working much when I first decided to do my 9" swap, but I've been busy as hell these past few weeks and will be for another 2 at least. Then hopefully I'll be helping a friend/neighbor with a remodel that's about 1.4 mile up the road from me 


If you do have to go job searching, good luck!

Thanks, I'll probably find some low voltage electrical work...

Do you suggest a 9" over an 8.8? i like the SF/FF options on the 9", but really don't plan on running anything over 33"s so I don't think it matters... Either way it's awesome to see someone near my age get a swap together and almost completed! Time for me to  buy a welder...

You can probably remove the whole piston and spring instead of leaving parts in there. 

Thought I would post for the record that, well... This won't work!   

Without the piston inside the proportioning valve, it leaves the bleeder hole open, at least on mine it did. So I tried doing it the same way as the dude in the thread on NAXJ that Mr Random posted, that is removing the o-ring and spring but leaving the piston. Even then, you have to bleed the prop. valve through the lines going to the master cylinder (as described in the first link Jeffy posted). Sorry if my description seems a bit vague 

But all in all, pedal pressure feels good although I won't really know until I get the Jeep running and can drive it tomorrow. But I feel it'll work out fairly well
