Project Repeat Offender Suspension And Brakes - Slow Your Roll

The stock '85 spindles won't work with the Strange Engineering adjustable struts. The strut mount on the early-model Fox spindle is thicker than the '87-'93 strut mount. To solve this problem, MPS Auto Salvage sent us a set of '87-'93 spindles, which will bolt right up.

The Steeda Drag Race springs and Strange Engineering struts went right in. With the suspension reassembled, it was time to focus on the brakes.

The stock spindles had to be modified slightly for the new Aerospace brakes. The mounts for the stock brake calipers need to be cut off so the new caliper mounting bracket sits flush against the spindle. Aerospace Components recommends removing as little as possible when cutting off the stock mounting ears.

Next, the original dustshield holes need to be drilled and tapped. These holes are where the new caliper mounting plate will bolt to the spindle. Use a 5/16-inch drill bit to open the holes, and be sure to drill as centered as possible.

Next, use a 3/8-16 tap to thread the new larger holes.

The new caliper-mounting bracket simply bolts to the modified spindle. The bracket should be oriented so the brake caliper will bolt on opposite to the steering arm.

Before installing the hub assembly, the bearings must be installed dry for test fitting. Install the bearing and bolt the rotor surface to the hub.

Before installing the hub and rotor, we weighed the new brake system to compare it to the old system. The factory brakes weigh in at a hefty 26.6 pounds per side; the new Aerospace Components brakes tip the scales at 18.1 pounds, for a reduction of 8.5 pounds per side.

Install the hub assembly and check for clearance between the rotor surface and caliper-mounting bracket. The rotor-to-bracket spacing needs to be 0.050- to 0.080-inch. This can be attained by using shim washers between the spindle and bracket.

Once the clearances are set, remove and disassemble the hub assembly. With the wheel bearing packed with grease, lube the seal lip and place the inner bearing in the hub. With the inner bearing in place, install the grease seal with the spring side facing the hub. Next, install the wheel studs and mount the hub assembly on the spindle; tighten until the bearings are fully seated. Slight resistance will be felt when spinning the hub. Install the cotter pin and tighten the nose cap.

The calipers are bolted on next. Make sure the bleeder screw is above the intake port on the caliper, and tighten the bolts to 35 lb-ft.
