G-Body with Wilwood Compact Billet Master Cylinder

Attached are some installation pictures from manualbrakes.com To run this setup, it is best to use a vacuum assisted brake pedal since it already has the hole for the new pin location for the manual brakes. Using the vacuum boosted pedal will give you a higher pedal ratio for more leverage and...

Piston area is usually more important than piston count. A single 2.5” piston caliper with a piston area of 4.9 square inches will have more clamping force than a twin piston caliper with a 4.12 square inches all other things being equal.

If replacing calipers, it would be best to go with the big bore piston caliper from Wilwood or Afco if you want to increase the performance of your stock brakes. The Wilwood 2.75” caliper actually weighs less than stock and will weigh less than the billet aluminum d154 style Wilwood caliper and...

http://www.manualbrakes.com/g-body.html Only thing you should need for this swap is a vacuum boosted brake pedal and change out the front calipers. The vacuum boosted brake pedal arm has a hole for manual brakes, the PM brake pedals does not have this provision. The pin that comes in...

Moog replacement upper arms are about $100 each from rockauto.com. Dorman brand is about half the price of the Moog. I find it hard to believe that pressing in 4 bushings is going to be more expensive than $100. Maybe I don't know the market rate for pressing in a bushings. Replacing you...

What will your brakes be used for? Street, drag, auto cross? For stock replacement calipers, Wilwood has some really good choices. If you currently run power brakes, I would go with the 2.75” Cast Iron Wilwood calipers. Cast Iron will deflect way less than the aluminum alternatives and give...

Yes. You will need the spindle, hub, rotor, and caliper assembly.

Are you talking about a larger diameter piston or a large diameter brake rotor? If you are talking brake rotor, then correct. If you are talking caliper piston diameter, then incorrect. I have tried a 2.75" piston Wilwood caliper and a 7/8" bore master cylinder. The 7/8" bore master...

Manual brake installation with adapter plate painted satin black to match firewall better.

I am done testing the manual brake setup with a stock, aluminum, rebuilt, 24mm bore, 1980 El Camino master cylinder. With only this change, I got back the brake fluid pressure that I lost when I upgraded to the Wilwood 2.75” metric calipers using the 7/8” bore master cylinder. I bench bleed...

1978-1980ish Malibu, El Camino, Cutlass, Grand Prix, Regal, etc came with manual brakes from the factory. They come with a 7/8 inch bore. If buying one of these from the auto parts store, measure the bore to make sure they are selling you a 7/8 inch (0.875”) bore and not the power brake...
