Brake Upgrade - Right side

Even though I got a late start today, I was able to get some work done on the Aspen. I was able to complete the budget big brake upgrade on the right side.

Budget Big Brake Upgrade

A little bit about the Budget Big Brake upgrade. The Aspen came from the factory with 10.87" front disc brakes. These were essentially the same brakes available on A-bodies (Duster, Dart, Valiant), and earlier B- and E-bodies as well as M- and J-bodies (Diplomat, Fifth Avenue, Cordoba, Imperial, Mirada) through the 80s. In the mid 70s, Chrysler's larger cars received larger 11.75" rotors. These included B- , C- and R-bodies. These 11.75" rotors are very easy to swap over to the Aspen.

From the junkyard, I snagged a pair of caliper mounting brackets from a 1980 Dodge St. Regis. I also ordered new rotors for the same car. Those are the only extra parts needed for the swap. Everything else (caliper & pads) are the same between the St. Regis and the Aspen, so I am able to reuse those parts.

Front wheel removed. Here you can see the aluminum spacer that I run to mount up the 17x8" Mustang Bullitt rims.

Here is a comparison shot of the 11.75" rotor from the Dodge St. Regis (left) and the 10.87" rotor from the Aspen (right).


New 11.75" rotor installed. Also replaced the wheel bearings with new.


Stock Aspen caliper and pads installed on the new 11.75" rotor.



BEFORE: Stock 10.87 rotors:

AFTER: New 11.75" rotors:


The new rotors fill out the 17" rims a little better, and should provide some additional stopping power. Tomorrow after softball I'll do the left side.
