amerdt4 Well, i'm still at a loss . Three more bottles of brake fluid and I cant figure this out . I went through the whole brake system , all lines , all connections no leaks . I had my father come and help me , we looked it over together , re-bled the lines . When the jeep is running my brake light is constantly on until I pump the brakes up and it seems like after that I have good compression but it goes away , the light comes back on .

89Saharagreen Ok so explain in detail how you bleed the brakes it is a fairly straightforward process.

Did you pump the brakes?

Or slowly push them as someone bleed?

Or did you bleed while someone else pushed?

It can take about 5 times on one position of slowly pushing and when they bottom the person slowly pushing ha to hold it down til you lock the bleed screw back then they can release otherwise your pulling air back in.

So start with brake farthest from the reservoir then work your way forward.

Also look for any leaks all bleed screws need to be tight before you stop and also open li to reservoir make sure it never runs dry

Then tell us what you have after all that!

OverkillYJ You should take the little O-ring out of the proportioning valve so it distributes the pressure evenly. Drums take more pressure to stop so the rear will get more then it needs. I kill back brakes way faster then I should because of that. Haven't gotten around to doing it myself yet. There are a few write ups on it though. Seems to be the easiest way to correct the issue instead of taking a proportioning valve from something else.
07-09-2013 06:57 PM
YJ fanatic I didn't need to swap proportioning valves. The brakes on my 8.8 stop my 35s better than my D35 drums stopped stock tires.
07-09-2013 06:48 PM
4Jeepn For the brakes on mine which was a 95 4.0L i was told i would have had to have changed the proportioning valve as early years pre 94ish don't work well with the rear disc. thus my 95 was gtf. again not sure but that is what I was told.. mine had no issues working.
07-09-2013 06:40 PM
amerdt4 Yeah , I'm just waiting for the OG's to chime in
07-09-2013 06:33 PM
AllMudd Mmmmmmmmm I'm stumped. Hope I don't have any issues. See if you can Pm OverkillYJ and see what he did if anything he as well has done the 8.8 swap.
07-09-2013 06:28 PM
amerdt4 No leaks , no air
07-09-2013 06:19 PM
AllMudd I've read that if you get the proportioning valve from an XJ then it helps but not sure. Do you have any leaks? If you bleed it again do you still get air?
07-09-2013 06:05 PM
amerdt4 Yes , I did RR , LR , RF , LF .
07-09-2013 05:58 PM
AllMudd Not to knock at you mechanical abilities or nothing but did you start at the right rear and let it gravity bleed? Or at least start there with the old have a buddy help bleed method? I am currently doing the 8.8 swap and am curious if I am going to have this issue too.
07-09-2013 05:47 PM
amerdt4 So have anyone of you guys done brake booster upgrades? Or master cylinder? I have bled my brakes like 5 times and when I stop the pedal pretty much goes to the floor . I slow down but no where near a safe stopping speed . I have 35's
06-26-2013 03:20 PM
OverkillYJ Yeah I am set up SOA. I welded bolts to the top of my tubes to bolt down the line to. My lines actually go over my springs to the calipers. When I bought my 8.8 i stripped it completely of everything with a grinder. That is why I dont remember the stock locations.
06-26-2013 03:10 PM
Norcal_Chris Factory location with SUA. The hardline is attached with a bolt to far edge in the back of the spring perch. Then the line goes up to the caliper.

All it takes is one good rock or log.
Ever have a rock in beween your spring and wheel? I have a bunch of times. We seem to have an abundance of skinny rocks that love to bash calipers

It is not that big of a cost to have the peice of mind of a stronger line, plus better brakes from the lack of a rubber line to swell under pressure.

Mine are on top of the tubes and tucked out of the way. I have been bushwacking with my Jeep, and doing seriously deep mud all the time and never had a problem with them. I have driven through crap time and time again that was so horrible you would have to hack your way through with a machette to try and get anywhere on foot. I also was just romping around on some of the Red trails at Rausch with no worries.

Although I did weld in all of the hard line mounts, maybe I moved them a bit? I cant remember for sure, but it would be one in a million for me to damage them.

amerdt4 I have replaced all the other rubber lines with Rubicon steel braided ones and wanted to keep it consistant . Plus i didnt want the rears to be the weak link in the system . Steel braids do have upgraded qualities in durability and rigidity . Plus I hear chicks dig'em.

By hell I mean milk shake consistency mud, and swamp crap with a bunch of stuff growing out of it hanging all off my axles. Never a problem.

The only one to worry about is the one from the body to the axle.

East Coast Gear Supply sells a whole brake line kit for the YJ 8.8 swap.

Get the teraflex upper shock bar. Beats the upper shock extensions IMO.

Exactly. You dont want to weld them low, you want to weld them high for more clearance. Then figure out what size shock fits best. Only downside is that you will need a different length shock for the rear and front.
