Brake Pedal Identification FAQs
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
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.
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.
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.
Manual brake pedals measured 2.0″ from center of pivot to center of pedal pin for all years 65-70.
Power brake pedals measured 5.0 ” from center of pivot to center of pedal pin 1967 – 1969. Boosters for 67-69 had curved input shaft
Power brake pedals measured 4.5 ” from center of pivot to center of pedal pin 1970 only. Boosters for 1970 had straight input shaft
Power brake pedal 1970 only. Note the steeper curve right below the pedal pin to clear the wider collapsible steering column. All 68-70 pedals have that offset.
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.
65-66 Pedal Support
64-1/2 Pedal support is identical except the square hole on the driver side, 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 67 – 68 power brake pedal pivots from a 3/8″ diameter bolt that goes through two holes up high in the support (The pedal support on the right).
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
69 Mustang and Cougar pedal support
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.
70 Mustang and Cougar pedal support
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 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.
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.

This template is used to modify the firewall when converting from manual brakes to factory type power brake booster on 67-70 Mustangs and Cougars.
Most important thing is the big hole for the booster must be raised up from the original master cylinder hole position.

Technical Information
FAQs
What bearings do I use for a 69 Mustang?
69 spindles have smaller axle on all except BOSS 302 and BOSS 429. 69 non-Boss spindles use A2 and A6 bearings. 70-73 spindles have larger diameter axle and use A12 and A13 bearings.
69 non-Boss spindles use smaller tie rod, same as 67-69 Mustang.
70 spindles use a larger tie rod that is a little larger than the 67-69 spindle, but smaller than the Granada spindle.
What hubs do I use on what spindles?
Hubs and rotors from 65-73 will fit either spindle as long as the bearings that fit the spindle axle are used. The OD of the bearings is the same for all years mentioned.
So, the 70-73 spindle has larger axle but the rollers in the bearings are actually smaller than the 65-69 bearing rollers.
Will your rear brakes work on the Torino (new style) bolt pattern?
Yes. The big bearing cobra rear brackets will work with the Torino (new style) bolt pattern using 3/8” mounting bolts and will also fit the older style large bearing 9” flanges using ½” bolts.
The brake gap needs to be 2.50”. That is measured from the outside of the housing flanges to the outside of the axle flange (where the rotor would fit, but not including the thickness of the rotor.
