I wanted to upgrade the brakes on my '54 Chevy BelAir from the under floor master cylinder to the firewall and add a brake booster. My plans for the car are to install a disc/disc setup and that requires a definite upgrade on the master cylinder. Speedway Motors had the perfect kit for my car. Part number 910-1951 is a kit that includes all necessary brackets and hardware to convert from a under floor pedal assembly, to a under dash pedal assembly and firewall mounted booster/master cylinder. So let’s get the installation started!
First off I had to remove the existing firewall access panel located on the driver’s side firewall. This panel is held on with Clutch Head screws and using the proper screw driver to remove them makes life a whole lot simpler. I luckily inherited my father’s tools, who was a lifelong mechanic and a MAC tool dealer for years so I already had the appropriate screw driver (Thanks Dad). I then relocated any wiring I thought might get in the way of the new pedal assembly and cleaned the area up.
Next, I loosely assembled the pedal brackets and booster mounts to the new firewall plate using the supplied hardware. Make sure the booster mounts are angled up. Then install the firewall plate and pedal assembly as one unit through the firewall access area in the engine compartment and secure with the supplied Phillips head screws.
Next up was to attach the pedal bracket to the dash. There are 2 "L" shaped brackets that attach to the dash and then connect to the new pedal brackets. If you have a '51-'54 Chevy, you will need to install the supplied union adapters to the steering column mount studs first or nothing will line up correctly! Also make sure to loosely assemble everything first or you will be untightening everything later, trust me. The pedal is then installed into the bracket and hangs down on the right side of the steering column. Once the pedal is in place you can tighten all the bolts up.
I had also purchased part number 91031411 which is a Dual 7" Brake Booster Master Cylinder combo kit in 1 inch bore to go along with my new firewall mount pedal assembly. I installed the booster which bolted right up to the new brackets and attached the supplied push rod to the new hanging pedal. For now my installation is complete.
I would definitely recommend this kit (Pt# 910-1951) for your '49-'54 Chevy cars. It relocates the master cylinder from under the floor to the way more convenient firewall location. It also gives you a much better brake pedal ratio by converting to a hanging style pedal. All the parts in the kit are nicely cut and all hardware is included for a seamless installation.
