Brake Components Selection Guide
Brake components work as a system, therefore it's important to select the right combination of parts for your vehicle based on model year and type of brakes. The guide below assumes U.S. spec vehicle.

- No brake booster
- No proportioning valve
- Wheel cylinders, front
- Wheel cylinders, rear
'71, stock with 4 wheel drum brakes:
- Master cylinder
- Brake booster
- No proportioning valve
- Wheel cylinders, front
- Wheel Cylinders, rear

- Master cylinder
- Brake booster
- No proportioning valve
- Wheel cylinders, front
- Wheel Cylinders, rear
'75, stock with 4 wheel drum brakes:

'71 and later FJ40 converted to front disc, but retains rear drums:
- Master cylinder - Either of Option A or Option B
- Brake booster
- Proportioning valve - OEM style or Wildwood Adjustable Valve
- Front disc pads - Depends on conversion

- Brake booster
- Proportioning valve - Wildwood Adjustable Valve
- Disc pads - Depends on conversion
* If you want to add a brake booster to a '70 and earlier or non-US FJ40 without an existing booster, you must first undertake a booster conversion. There are 2 known methods to achieve this:
- Use an adapter. This will entail lengthening the booster rod on the cabin side to compensate for the extended distance
- Modify the firewall
