Pedals & Boosters Identification

64-1/2 & early 65 had this type of pedal pin. (Brake light switch was on master cylinder instead of pedal pin)

Unique to 68 Manual Brakes. Bracket appears to have been designed to hold a switch, but was never utilized for that purpose. Acts as a positive stop for the pedal's upward travel.

67 Power brake pedal. Note the notch in the pedal about 1/2 way between the pivot and the pin. That notch gives extra clearance around the clutch pedal shaft when used on manual transmission cars.

All pedal assemblies had 4 of these plastic bushings.
Two go in the brake pedal pivot.
Two go into the pot metal bushings in the pedal support.
They seldom wear out on automatic cars, but almost always wear out on manual cars.

WHAT FITS WHAT…?

Brake pedals are identical between manual transmission and automatic transmission, except the foot pad part.

A pedal from an automatic car can have the foot pad trimmed to fit on a manual transmission car of the same year.

65-66 brake pedals are same for manual or power brake cars.

67 manual brake pedal will fit in 65-66 as exact replacement. 65-66 pedals will fit the 67 car.

68-70 manual brake pedal will fit 65-70 and work fine but has more side offset. Foot pad winds up in exactly the same spot, though.The foot pad is wider on the 68-70.

65-67 manual brake pedals will NOT fit in 68-70 car due to the wider steering column. (Fits but not well)!

67 power brake pedal will only fit 67 car.

68-69 power brake pedal can be utilized in 67-70 car as long as the 67-69 booster is utilized.

70 power brake pedal can be used in 67-70 car as long as the 70 booster is utilized.

70 booster cannot be used on 67-69 power brake pedal

67-69 booster cannot be used on 70 power brake pedal.

IMPORTANT:
On cars with manual brakes, the steel lever arm you see welded to the top of the pedal serves as a stop to keep the pedal from being able to travel back towards the driver far enough to pull the pushrod out of the master cylinder. If the rod comes out of the master cylinder, there will be no brakes. Most master cylinders for manual brake cars have a positive rod retention clip built into the piston. The rod snaps in place and is very difficult to get out. MOST DISC BRAKE MASTER CYLINDERS DO NOT HAVE THAT FEATURE, since they were mostly designed for use with a power booster. When swapping master cylinders and brake parts, BE SURE there is no way the rod can be pulled out of the master cylinder, by either a positive lever stop on top of the pedal, or by positive rod retention clip in the master cylinder, or both.

74 Maverick non-power disc/drum master cylinder with 15/16" bore is very popular and has the clip 67-70 Mustang power disc/drum master cylinder with 1.0" bore does not have the clip.

64-1/2 Pedal support is identical except the square hole on the driver side, (denoted by a red square in the picture) where the clutch pedal stop bolts on, is a 1" long vertical slot so the clutch pedal height can be adjusted. That is an easy mod to add to a 65-66 by simply slotting the hole.

The 69 power brake pedal pivots from a 3/8" diameter bolt that goes through two holes up high in the support. The hole locations are shown by a yellow marker in the picture. The manual brake pedal pivots from the pot metal bushings.

The 67 - 68 power brake pedal pivots from a 3/8" diameter bolt that goes through two holes up high in the support. The holes locations are shown by two yellow markers in the picture. Early 67 pedal supports did not have the 3/8" holes. If adding the power brake pedal, the support must be drilled. Hole location is critical for the pedal to fit properly.

The 70 power brake pedal pivots from a 3/8" diameter bolt that goes through two holes up high in the support. The hole locations are shown by a yellow marker in the picture. The manual brake pedal pivots from the pot metal bushings.

Typical installation of brake pedal and stop light switch.

67-69 Midland (clamp type) power brake booster Note curved end on the input shaft on the left.

67-69 Bendix (crimped type) power brake booster Note curved end on the input shaft on the left. This booster requires a spacer between the booster and firewall.

67-69 Midland (clamp type) power brake booster Note spacer on front of booster where master cylinder bolts on.

67-69 Bendix (crimped type) power brake booster Note curved end on the input shaft on the left. This booster requires a spacer between the booster and firewall. Spacer is shown clearly in this picture.

1970 Bendix booster is identical to the 67-69 Bendix booster with the exception of the input rod being straight instead of curved.

MustangSteve SPECIAL... Get a Bendix booster with a new power brake pedal (for automatic or manual trans) for $300.00. This will fit 67-70 Mustangs and Cougars. Use template shown below.
