Mopar Big Brake Upgrade on Manual - Booster / Master Cylinder
 

Im about to purchase the Mopar Brake Kit, since my stock brakes are struggling with my 38's... and Im going even lower geared with an Atlas 4.

I've found multiple references to issues with the manual transmission and install of the master cylinder / booster... specifically with the reservoir.

Im look for some specifics on what the fix is... i.e. part numbers, details etc...

Also, does anyone have a preference for rear brake options.

Perhaps consider the Dynatrac ProGrip kit? I'm running this kit and am pleased. No need to replace the MC and comes with all four discs.

It does a great job of braking with 37s and holds me in place in 4LO (my OEM brakes didn't) with my 6.0L and 6L80E.

I realize that your Atlas4 will give you a much lower overall gear, but figured I'd throw it out there.

Yeah. After more research, I think this is what Im going to end up doing.

I will probably end up with 60/60 PR in a year or two, and will do the MC at that time.

:thumbsup: I think you'll find that the ProGrip kit will do a good job for you.

In the Mopar install instructions, it states you need to install a clutch reservoir. Call Mopar and ask them to provide you a Part Number of what you need.

X2 on the Dynatrac ProGrip system. It is a complete bolt on kit, with nothing else needed, and it is a huge upgrade over stock. It also doesn't change the pedal feel like some of the other kits out there. Highly recommend.

Thanks Ryan! We're always happy to hear feedback like this!

hahaha... I guess I'm chopped liver... :D

Not at all Jed. We think of you as the finest caviar!

Jokes aside, thank you for your feedback and we're glad you're a vocal proponent of the ProGrip system and Dynatrac products!

Just giving you some flak. :cool:

Seriously though, one of the better upgrades I've made to my Jeep and provides enough increased performance that I see this as a necessary part of moving to larger tires / heavier rigs.

The one they recommend costs $100!!!!! You can get the exact same reservoir from a motorcycle parts store for a fraction of the price, and it's the same size.

Yeah, I don't have a manual so I never had to look into it further. If you have the info on the motor cycle resevoir that seems like useful information to the OP's question. Even at an additional $100 that would put the Mopar BBK at $800 which is still below the cost of most other brake upgrade solutions, where replacement pads, calipers and rotors are also more widely available since replacements for these parts which normally wear out can be found at any autoparts store and a multitude of online retailers including aftermarket alternatives.

Bigger booster, and MC filling and providing more pressure in pushing larger calipers is a more complete brake upgrade solution. Sure you can get by with just adding larger rotors, and calipers while re-using the stock booster, MC and notice an improvement in braking but when you understand the entire brake system, you also are able to realize that it is further beneficial to upgrade the additional components to match the use of adding larger calipers and rotors. It's like upgrading your suspension by just adding taller springs and shocks. Those parts will give you the lift you wanted, but adding in the longer control arms, sway bar links and trackbars is what gets you closer to where you really want to be to get the most benefit out of that suspension lift upgrade. It's the same with your braking system.

he sold me! ProGrip added to the list after I install my lift 👍🏼
