Master Power Disc-Brake Kit - Brake It Up!

With the four fasteners removed, the whole axle assembly can be pulled from the axle housing. The object is to remove the drum-brake backing plate.

Before proceeding, a steel spacer is installed over the axle to compensate for the thickness lost when the old backing plate was removed.

The axle goes back into the axle housing with the spacer in place. Here, new fasteners are used on the assembly, which now incorporates the primary caliper-mounting bracket.

New cap screws are inserted into the primary caliper-mounting bracket, and each is then fitted with a spacer sleeve. These sleeves will locate the secondary caliper-mounting bracket the correct distance inward.

The secondary caliper-mounting bracket is placed in position. All fasteners in the kit are retained with nylon locking nuts, making them impervious to loosening due to vibration.

With all of the caliper-mounting hardware installed, it is a simple matter to install the new rotor onto the axle flange.

Here the Master Power rear caliper is placed on the new brackets. It's a perfect fit. The floating aspect of the caliper design means the caliper moves to compensate for pad wear.

On the backside of the rotor, we see the brake lines being attached at the caliper. If the copper washers are not in place on either side of the hose fitting, there will be a leak. The other end of the new lines attach at the hard lines on the axle.

Here's the completed rear disc-brake installation. Next, the new master cylinder was installed, and the whole system was flushed and bled free of any air. We're confident this new four-wheel disc-brake setup from Master Power will give our Cleveland-powered Mustang the whoa to match its go.
