Manual Brake Conversion Kit, 1979-93

By: Maximum Motorsports


  • Parts used when converting a Mustang from power brakes to manual brakes. Includes new pedal arm, firewall adapter block, pushrod, and hardware. Does not include master cylinder or brake lines.

    This kit fits

    • 1979-93 Mustang
    • Direct replacement master cylinders for 1979-95 Mustangs
    • Aftermarket master cylinders (such as Wilwood) that fit 3.20" to 3.22" mounting stud spacing, and have a shoulder less than 1.6" in diameter
    • Manual transmission pedal box
    • Automatic transmission pedal box


    • Alternative to vacuum-assisted brakes that no longer function properly because of low engine vacuum.
    • Consistent pedal feel because the pedal effort no longer varies from fluctuating vacuum level.
    • Reduces weight.
    • Pedal effort is reduced, compared to reusing a power brake pedal with a manual conversion, because the MM pedal arm has the proper leverage ratio for manual brakes.
    • The pedal feels firmer because the MM pedal arm is much stiffer than the stock pedal. This quickens brake response and improves modulation.
    • Firewall adapter block mounts the master cylinder at the proper angle for correct pushrod alignment. A misaligned pushrod will damage the master cylinder piston seals.
    • Pedal pad height (the pad distance from the firewall) may be changed for easier heel and toeing.
    • Quickens brake response because it eliminates the motion lost by the stock brake light switch attachment design.
    • Time Required: 4 hours (approximately)

    • Skill Level: Intermediate - You should have "above average" mechanical knowledge/experience to attempt this installation.

    • Mustang 1979-1993 GT

    • Mustang 1979-1993 LX
