Installation of the rear IRS Wilwood brakes

rear IRS Wilwood brakes: Rear Wilwood layout

The rear suspension is complete. Therefore the next phase is the rear braking system.

First, the layout is nearly identical to the fronts. However, a few details change.

Also, the rear calipers are top-load for brake pads. As a result, pad swaps feel simpler. Still, the rears are about 2X less likely to need pad changes.

Besides that, each rear caliper has a parking brake mechanism. In other words, a smaller mechanical brake sits on each side.

Then I laid out all the parts. Next I mimicked the directions. So the install was simple to repeat on the other side.

Ultimately the installation is pretty straightforward. First you attach the brackets to the wheel spindles. Then those brackets hold both the main and parking brake calipers.

Calipers and parking brake

Next you mount the rotors just before the calipers. After that, you measure the clearances too.

Fortunately, this kit is well built. As a result, only the basic number of washers and spacers were needed.

Floor cleanup and lug tips

Meanwhile, the floor looks much cleaner. That is because the rear suspension and brakes are on the car!

Also, I installed a few washers on the lugs. Therefore things stay tightened up and do not wobble around.

Likewise, I have all the lugs installed. Ultimately I figured I will get nicer bruises instead of scrapes with the rounded lugs 🙂
