Howard safety wired the hat bolts to keep them from backing off.
Time to remove the stock rear brakes.
We first removed the stock rear brake lines.
Then the stock rear caliper.
You can see how the new 4 piston Wilwood calipers have much more brake pad area. What is amazing is the Wilwood caliper is much lighter than the stock small single piston iron part.
The 327mm Wilwood rotor dwarfs the stock part. Despite the size and braking power difference the Wilwood part is much lighter.
