CONFIRMED! Heavy duty brake bolt on in place of ND brakes

Here is the shopping list below:



68052372AA
front caliper mount code BR6 Left
68052372AA
front caliper mount code BR6 Right
68035012AB
front brakes, rotor Grand Cherokee w/Heavy Duty Brakes x2
68052380AA
rear brake caliper Grand Cherokee Right w/Heavy Duty Brakes
68052381AA
rear suspension, brake components, caliper Left
68052374AA
rear suspension, brake components, caliper mount code BR1 & BR6 Left or Right x2
68035022AB
Rear brake rotor Grand Cherokee w/Heavy Duty Brakes x2



Only the front rotor is 350MM

The rear rotor is exactly the same diameter as the solid rotor at 330mm just the width has changed due to the vented portion

Here is the good news if you have the 17" wheels and want to add vented rear rotors you can do it.

Here are the pictures showing the parts with differences.


Here are the new parts minus the rotors


The new front caliper adapter on the left and the Standard duty on the right




Here is new front rotor installed along with the new adapter and the existing front brake caliper.


Here is the new rear caliper in black (the difference it the width across note the hole on the black one is larger.)


Here you can see the difference in placement of the rotor path in the adapter.

Everything came up to $511.00 for the brake parts. It could have been cheaper if the rear calipers didn't have a core charge.

If you can pick up the rear calipers and adapters in a salvage yard you may be able to come in at a lower price.

I had to order a Door and they were shipping it by pallet so I don't really know what the shipping was if it was based on weight.

The front rotors and caliper adapters are pretty heavy.

The rear brake components are reasonable light.

I am hanging onto to all the parts since the other jeep can use them. Or I may just upgrage the rear brakes on the other jeep to vented since they will still fit under the 17" wheels

Great Job!
I have a few questions regarding the job. Were the bolts that hold the caliper brackets reusable or were they stretch bolts and do the bolts that hold the caliper in lace require locktite and do you know the torque settings for those bolts?
Thanks.

As far as I know the bolts are reusable.

Yes loctite is a must.

I don't know what the torque settings are, I don't own a torque wrench either.

I see the front caliper is black and has a Mopar symbol on it; where did you get those? I thought all the parts were basically a zinc color as the old ones you have?

Some one will have to chime in on this one.... As far as I know it has been said you get HD brakes with the tow package on V8 equipped Limited/Overland/Summits

HD brakes are not available on laredo trim

Correct, not available on Laredo.

That's why I want to do this mod; stupid to leave it off of the same equipment due to trim level.

excellent information.

Does anyone know if tye Limited V6 with the tow package gets heavy duty brakes or is it engine dependent? i know that you get heavy duty cooling (larger radiator) with this tow pkg. But I did not now about the brakes.

On the 11-13's you had to get the V8 to get the heavy duty brakes, on the 14 though who knows. If that is what yours is look at your back brakes, if they are vented you have the HD brakes.

The caliper is the same:

The improvement in the braking comes from two things:
  • Larger diameter (This gives more mechanical leverage on the axle)
  • Larger surface area (this give more area to dissipate the heat over)
The rear brakes only benefit from the added surface area created by adding the ventilated rotors.


The noticable benefits I have observed from the installation of the brakes are as follows:

  • The brakes have less likelihood of the front wheels locking up
  • There has been less instances of Nose dive under heavy breaking
  • The brakes are easier to modulate
  • pedal feel is more linear
  • I have not done any hard measurements but the stopping distance seems to have been reduces.
I am guessing that if you did just the front axles that you should see a great improvement in stopping. Also just doing the front is more cost effective as you would only need the caliper adapter and the front rotors.
