JeepcoMJ Posted May 31, 2018 Share Posted May 31, 2018 In the middle of my 97 conversion, limited slip d44 with kj discs. Thinking of doing away with the cable brakes, definitely doing away with the parking brake pedal. Bleeding this won't be a problem, I'll pressure bleed it with some aviation equipment I've got at work. I'd worry about leaks except i deal with hydraulic lines on interior every day and seldom is it an issue. It would act as a line lock, as well. Thoughts? Located @ xj parkparking brake slot in console. Link to comment Share on other sites More sharing options...
Jeep Driver Posted May 31, 2018 Share Posted May 31, 2018 I'll eventually do the same but with dedicated calipers. T'ing into the existing line? no. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted May 31, 2018 Author Share Posted May 31, 2018 May be worth it to put a parking disc on the transfercase output for it. Link to comment Share on other sites More sharing options...
AZJeff Posted May 31, 2018 Share Posted May 31, 2018 It should work just fine. But..... For most applications, a mechanical parking brake should work fine. The idea of a mech. brake is that it is used for added 'locking' of the vehicle once it's not moving. That works well under two conditions: (1)the brake is not left applied partially and you drive off, dragging the brake and burning up the parking brake shoes. and (2) the parking brake does not freeze "on" in certain climates because of water in the parking brake turning into ice during an overnight parking situation. (This happened to me on a 1961 Ford when I was a kid, and it sucked.) If you have properly adjusted parking brake components that are adjusted, and the cables are lubricated and adjusted properly, the mech. parking brake does just fine. Deleting it is more a case of a personal experiment, rather than necessity of improving a deficiency. Just my $0.02... Link to comment Share on other sites More sharing options...

For those of us who have gone discs with the mini drum in the rotor...........they SUCK! Those cannot be trusted. Link to comment Share on other sites More sharing options...
JeepcoMJ Posted May 31, 2018 Author Share Posted May 31, 2018 It is more of a "hydraulic brakes hold better than mechanical" and "less parts to install". As it stands, I need to convert the xj brake and mj cable to fit, which I really just don't feel like doing. Link to comment Share on other sites More sharing options...
Jeep Driver Posted May 31, 2018 Share Posted May 31, 2018 https://www.summitracing.com/parts/wil-250-5364?seid=srese1&cm_mmc=pla-google-_-shopping-_-srese1-_-wilwood-disc-brakes&gclid=Cj0KCQjwl7nYBRCwARIsAL7O7dHHFZmK5gAJhn6dzUE-eT6X83sKYQXB9ElDxWusUW0BUAiizbFPq1gaAqhkEALw_wcB This is the way to go, IMO. Those with 8.8s could easily set this up with the 9" conversion ends. I can foresee countless situations whereas a handbrake would be the $#!&. Not just a parking brake. Managing a steep incline while working a clutch, for one. No, not cheap, but worth the effort. And yes, hydraulic over mechanical? hydraulic.

I didn't have a problem with them on my MB240D. The ones on my XJ do need work though. Link to comment Share on other sites More sharing options...

They worked OK on my XJ, but I will admit they need to be adjusted VERY carefully. Even then, I would not trust them to be the only thing holding the vehicle on a serious incline. That's what "Park" is for, or putting it in gear with the engine off. To be honest, even the conventional parking brake on the Bendix-type drum brakes isn't the greatest, as it tends to work better against forward rotation than it does backward movement.
