My Teraflex Delta Brakes Thread

[DocMcStuffins]

I need to find someone local so we can make that determination. I test drove a rubi and the brakes didn’t jump out at me, but were not bad or anything. Also 37” vs sub 33” tires and smaller wheels so the rubi would be interesting to test when same setup. The sport brakes were so obviously poorly matched after upgrading. I should not have to think about braking that much when driving.

Welp- I am in Fresburg so if you are ever in my neck of the woods let me know!!!

Awesome- that's what I was thinking! Thank you. How much of an upgrade from the OEM JTRD brakes do you think the Delta kit is???

Quite a bit! The Rubicon and higher levels that come factory with the "big brakes" with the dual piston front calipers have a rotor diameter of 12.9 inches, where as our Delta rotors are 14 inches in diameter. Having the larger diameter rotor gives more leverage for more stopping power, and better cooling abilities as @dcmdon pointed out. Also, since the Delta calipers a 4 pistons per caliper, the clamping force is considerably higher and more even with 2 in board pistons and 2 outboard pistons. On the rear it's an even larger increase since the factory rear caliper is only a single in board piston. The Delta kits have 14 inch diameter front and rear rotors, and 4 pistons per caliper.

Combined altogether and it's enough stopping force to put you through the windshield if you don't have your set belt on!

Wanted to have an expanded thread on the Delta Brake kit. Installed recently they bolt on and do not require a new master cylinder. They upgrade from a single piston to a 2x2 setup providing improved clamping. Rotors also get upgraded to larger and slotted units. The kit was around $2600 and I paid in the realm of $700 for install.

They fit with my Icon Rebound 17”x8.5” with 4.75” backspacing no offset. Fit with no rubbing. There is a bit less room overall over stock units so I could see mud maybe jamming up in there, but I am not going to worry about it. Will get him dirty then if it ends up an issue can go from there.

I have been motoring around town and have been enjoying the extra stopping power. When I first picked up the truck I was not thinking about the new brakes. I also had big upgrades in front and back anti-rock and falcon sp2 shocks done at the same time. Was busy minding how the rig worked itself around corners and what the sway was like with the ARs. The brakes just do their job. This is to say they stop the rig nice and smooth and with good pedal feel. There is no persnickety trade offs that I can find yet. My guess is that’ll be how it is going forward. Basically OEM++on road.

I have not been able to do any hard off road adventuring but did drive over some dirt berms and a few rocks ? they have some bite for sure. At slow speed say 5ish mph when I get on the brakes its instant stopping power while the OG brakes had a bit of what I can only describe as delay for the full power. Like when pushing the pedal hard it had maybe 40% at first then over 1-2 seconds it reached 100% What I am saying is you get the full 100% when you push hard instantly. Its a bit to get used to. Not to say it doesn’t modulate. That was one of my worries, that this upgrade would make braking more binary. Not the case! I do think the way the stock brakes work is kind of nice, seeing it sort of modulates for you on hard braking. Deltas you can do that yourself but ups the difficulty a bit. Guess just part of the learning curve.

Downsides? Well the cost seems to be were those lie. Besides initial cost there will be an uptick in pads and rotors over time. My hope is those consumables last longer than the stock ones would being they are higher end.

Street driving stresses brakes more than 90% of off road situations. So don't worry about not getting your money's worth.

The size bump from 12.9 to 14 is about much more than increased leverage. Its about greater ability to shed heat. Because that's what brakes do. They turn kinetic energy into heat energy.

Smaller brakes to shed the same amount of heat in a given time will get hotter. So all else being equal larger brakes run cooler. Which means less chance of warpage.

Combined altogether and it's enough stopping force to put you through the windshield if you don't have your set belt on!

That's not really what its about. The factory brakes are strong enough to lock up the wheels and will put you through the windshield just as well. What the stock brakes don't do is shed heat like your larger rotors.

4 piston calipers give better pedal feel. But that's an intangible. You could probably get equivalent improvement in pedal feel by replacing the stock lines with braided steel aeroquip lines.

The big benefit is the rotor size bump, which increases the brakes ability to shed heat. The calipers are eye candy in most street applications. (Which is fine, eye candy is good) But its too bad someone doesn't make a big brake kit with larger rotors that use the factory calipers. That would give tremendous band for the buck. You would need new caliper brackets to locate them out further.

You also probably couldn't go as large since the stock calipers probably have a thicker spine.

bakoboddy, thanks for the honest review! It's good to see customer feedback on our kits.



We keep 100's of replacement parts on hand in our inventory, from rotors, to caliper piston seals, etc. We do our best to carry service parts should a kit be discontinued; we still have parts to old TJ lift kits that haven't been sold in over 10 years. Currently we do not have any plans to end production or discontinue the Delta kit.

The rotors and most of the caliper parts will be unique to the Delta kits, but the brake pads and related parts are from a 2015 Toyota Tundra.

Would you kindly point me to the tundra pads I need? Have put around 20k miles on these brakes thinking I will probably replace pads in the next 6-8 months.

Brakes have held up with no issues. When I get in other cars I am surprised how much more pressure I have to use to stop at similar speeds.

Sounds interesting but have never had any concerns about stopping with the stock setup. I'm reaching over 50K on original brakes and haven't had any issues - I will taking it in for service/check soon.

The JL on the other hand would benefit from this. I think the Wrangler brakes are very different in feel that Gladiator ones but that's a thread for another forum. LOL.

Happy its working out for ya!

We do not have a "direct" match for the pads we use, but they are very similar to the Hawk LTS pads in pad material. Spec wise anything that fits a 2015 Toyota Tundra will fit.

Any issues with leaking from the check valve? That was a problem for me, despite torquing to spec. They advised to go a couple lbs over, which seems to have fixed it - but damn it felt bad cranking into the caliper like that.

Overall I like mine, but I feel it takes lot more travel to get to full stopping power.

I have this very issue right now on my wife's JL , 3 out of 4 bleed valves leaking not pouring out but the fluid drip has already marked the inside of a wheel
25ft lbs already seems hellish tight for a thread that size i'm worried about going any higher , stripping the thread etc I have sent a tech support request to @TeraFlex so will see what they say .

This is a common problem on some aluminum brake calipers. The 4 and 2 piston big brake Akebono calipers come to mind. Get them hot and they leak.

Definitely been my least favorite mod to the Jeep. That or the side cameras/monitor system I put together, but that was all custom sourced by me. For the price, @TeraFlex dropped the ball on these imo.

Does anybody have an update on their long term usage of bigger brake kits?
Be it the Teraflex bigger brake kit or some other brand?

I’ve seen this somewhat discussed on other threads, but figured I’d ask here. I just had the Delta Brakes installed on my 2021 Gladiator a few days ago. They work great except they squeak quite a bit at lower stopping speeds.

Is that expected as part of the break-in period for the rotors/pads or should I get them looked at by the installer?
