Well this is a bummer. I knew I was due for some replacements because the fronts were making some squeaking noise this week. I just went out to my JK and noticed brake fluid on the ground at the right front. Brake fluid reservoir was low and I now have no front brakes. I topped off the brake fluid and still no fronts.

Waiting for the new mopar kit to arrive is now gonna suck.

Guess who isn't able to go to work today and is going to be doing some work on their brakes?

 

I found this interesting while shopping around for rear rotors.

The stock front rotor diameters are 11.89"
The stock rear rotor diameters are 12.44"

and here I was searching for rear 13in rotors to match the Mopar 13in Kit rotors.....stock are just a 1/2 in smaller.

 

Hmmmm??? I just checked on the status of my order for the Mopar kit to see when it would be in and they sent me this message:

"This kit does not include the master cylinder reservoir... Mopar Performance informed me that you will need to supply your own reservoir. We will go ahead and process the order for you and let you know when it arrives from Chrysler. Sincerely, Jon - moparpartsdiscounted.com"

Now I'm wondering if my current master cylinder reservoir will work, or do I need to go find one?

 

I just found this pic that someone else posted of the Mopar Kit. It doesn't look like it includes the MC reservoir. Now, I have a big mystery to solve to determine if I need to purchase one that fits it, or if I can re-use my current MC reservoir.

 

Interesting. It looks like the adapter bracket is not offset. If the caliper mounting holes are spaced the same as stock, then that adaptor could be used to install the BR6 brakes while re-using the stock caliper. When you get them in, would you check to see if the stock caliper will mount to that adapter?

 

Since my front brakes went out on Friday, I spent a good part of my weekend doing all the front/rear dis-assembly to be ready to jump into the install when all the parts arrive. So it will be pretty easy for me to do some side-by-side pics of the caliper mounting brackets to see the differences, if any.

However, looking at that pic that mounting bracket does look very similar to the stock one that I pulled off from the front last night.

 

I reached out to the vendor to see if they had any further details in regards to the MC reservoir. They didn't have the answer, but provided me with the Mopar performance parts phone number.

Here's the details in regards to the MC reservoir.

If you have an automatic trans (which I do) then you can re-use your stock MC reservoir with the kit. If you have a manual trans, then you will need to purchase an additional MC reservoir for the kit. For the manual trans, they explained something about the clutch actuator being connected to the MC where the stock reservoir did not fit the kit.

My kit is supposed to arrive tomorrow.

 

Well, I received the Mopar BBK kit today as promised. I'll make a separate show and tell thread with more pics. I'm currently working on getting this all installed, so I can get my JKU back on the road.

One correction in regards to the Master cylinder reservoir. The kit does come with a MC reservoir. When looking at the new MC, I was able to determine the stock MC reservoir would not fit. The reservoir connection holes are spaced differently and the reservoir mounting points are different as well.

So much for relying on the information from the experts at Mopar performance parts for the correct information.

I think they were confused. Where they were confused is that if you look in the Mopar Wrangler Performance catalog, it lists the BBK. Then directly under that is a listing for a "Performance Master Cylinder and Booster" for an additional $245. What I read previously, is that if you have a manual trans then you will need to additionally purchase the performance MC/Booster as well due to the clutch connecting to the booster and having connections that connect up to the brake MC and those connections are not available in the standard kit's MC/Booster.

Here's the page from the catalog that show this.


For now, here's a pic showing the complete contents of what all comes in the Mopar BBK that I got. The caliper brackets are the same shape as stock with no offset, but much larger and more heavy duty. Same for the calipers. So you won't be able to just purchase the Ram 1500's calipers and 13in rooters, without also getting the caliper brackets as well. I have a few pics that show this more clearly that I'll post later.


You won't be able to mount the stock caliper to the new bracket or vice versa.

 

Ok, I just ran into a major snag in removal of the stock brake booster.

Anyone who is more wrench saavy than myself (which isn't much), have any tips/suggestions on how to go about removing these nuts which are holding the brake booster?

The booster is currently mounted where the nuts are in a position where the firewall is preventing me from being able to get a socket on the nut, and the nut is below the sheet metal of the firewall so I can't get an open end wrench on it, even if I could reach it with an open end wrench.

 

I just finished installing this kit too. The instructions say to remove the booster and adapter plate as a unit. (4) bolts on the engine side of the firewall. Be sure to remove the clip on the brake pedal too. I also had to adjust my brake switch to fix my brake lights always being on.
