Jeep Won't STOP?! One Ton Axle Brake Fix!

Ever since we upgraded our Jeep Wrangler JLUR to one ton axles a few years ago, our braking capability has been an issue. Especially off road, on the trail in 4 low. Finally, though, we may have found a solution...

"Four Years of Bad Brakes"...sounds like a B movie! Once the booster was changed, those hard stops really lift the weight off the rear axle and tires. Watch for spinouts...or maybe a new game to play! Sounds like a great new adventure on the way to Jeep Beach - Looking forward to it! LiteBriteNationHardBrakes!

You’re mentally stronger than me because I’d be nuts if my high end super Jeep didn’t have proper brakes for so long. Sounds like it was a nightmare scenario and I hope you guys are finally over the hump on fixing it!

I think I've seen every video...too cool!!You guys keep making me want more. 12 years hard core Harley club, most positions. Now 68 and got my 2nd jeep. It's a 392...just heard you talk about Florida...I gotta find a schedule. Sounds like a hoot for this Memphis boy..Ha..Happy travels. I'll catch up to y'all before I get old and specially before I grow up.haha

When I did the 60/ 14-bolt swap on my JK, we used the 1-ton Ford/ GM brakes (dual piston calipers all around) with upgraded rotors and pads. I still had a soft pedal and brakes. The 1-ton brakes were massive compared to the stock brakes, but still fit under 17" wheels. Ended up upgrading to the J8 booster/ master cylinder to provide adequate fluid capacity for the larger pistons in the calipers. Brakes worked great after that, even during emergency stopping.

Great jeep content! Makes my day when New videos are posted.

My 79 Ramcharger w/1ton axles assembly. 39s, Big Block. Weight with top off about 5, 000lb. Added a booster and proportioning valve off a 1 ton dually. Stopped on a dime.

I would have upgraded the master cylinder to a 1ton 4x4 possibly the entire brake system. Good thing you put this out to us! Thanks!

I would pull up beside a truck with the 1ton version of your axles and compare the caliper brackets. There should be a bigger bracket for the axle model. Unless it's a Dynatrak knuckle and that's the problem! In that case you'd have to design the bracket for the knuckle and desired caliper.

The J8 booster made a tremendous difference on my 1ton JKU for stopping

Auto Parts can be exasperating! I run Kevlar pads on my '16 Ram 1500, with amazing stopping power. My wife's '18 Ram 2500 has very strange brakes. Most the time the brakes work fine. Other times it don't wanna stop!!! I first upgraded to a better semi-metallic pads for some improvement. I did order carbon-ceramic pads. But apparently the issue is the anti -lock brake controller block. Apparently complaining to the Mopar Hotline can get a new anti-lock controller block for no charge.
The stronger booster, and better pads are good upgrades. But the JT being fine, should support the idea of the anti-lock system being the root problem. But enjoy your upgrades too!

My gladiator with Dana ud60s with the f250 brakes stops on a dime with 40s and 17 inch wheels in high and low. One ton brakes for the win!

[bullittdog]

When I built my Jeep I couldn’t come close to affording Dynatrac’s so Superduty’s had to do..f350 brakes combined with 1500 Ram master/booster are spectacular.

Regarding the electrical issues, we were group wheeling and had to wait a lot. Once I started up and put in drive quickly and took off. Got an engine light and lost 4 low and got wheel censor codes. Wheels started locking up because the vehicle thought we were in a slide. Cleared codes on the trail and made sure the computer cycled fully then all was fine for the rest of the day.

Guys look up power brake. They a small south african company but are is in the USA. They could assist, give them a shout. We have a big brake upgrade with new clipers and discs that fit under 17inch rims. They do alot of kits in the Dakar aswell.

[Minnesota_Vance]

My 392 does the slow stop and often slides on the trail without locking up the wheels just like you described. I asked about going to eight lug breaks and was told they would give me that much of a performance advantage for the money. So I still have stock breaks and just keep in mind that my rig isn't going to stop on a dime.

Been runnin ebc dimpled slotted rotors and ebc 6000 series pads for years. Never squeals but definitely dust. Stops great, 2004.5 Cummins.

I talked to you in Moab, it was the LF wheel speed sensor 😉Glad you got it figured out.

Changing the proportioning valve on atmospheric side to allow more + positive pressure. Then couple that with a lighter return spring on the vacuum side, generates more hydraulic pressure.

[sheinz]

I suppose newer is Not Always better. My 79 dana 60 swap stopped my 46's dead at any speed, and with stock ford calipers and pads and the best thing was 16 inch rims. CHEERS AND SAFE TRAVELS Steve h

Replacing the rubber brake lines with braided brake lines helped me a ton. The stock rubber brake lines expand under pressure like a baloon.

Can't say many good things about my DStrac axles, but the brakes work great. Stock 2.0 JL booster and master. V8 swap. Locks ups 42s.
