Aluminum Drums
No drilling required. Bolts can be knocked out from outside of drum and installed from inside drum, using hammer and drift.
1965 CHEVELLE, CHEVY II & CORVAIR FRONT BRAKE ANCHOR PIN CHANGE & SERVICE CAUTION - New brake anchor pin is used which requires revision in steering knuckle, flange plate, and anchor lock pin. Both type parts are available in service kits; however, either all first type or all second type parts must be used. Do not mix. When installing new type pin, torque to 130 ft. lbs. before peening tabs on lock.
1965-66 PONTIAC & TEMPEST FRONT WHEEL HUB & DRUM BOLT REPLACEMENT NOTE - To avoid drum damage, support drum in area of bolt being removed with pipe, or other suitable sleeve-type device. After bolt is pressed out, clean hole by drilling with 41/64" drill (Pontiac), or 9/16" drill (Tempest). Use replacement bolt number 9785351.
1967 & EARLIER PONTIAC FRONT BRAKE HOSE REPLACEMENT NOTE - Whenever replacing hose on any applicable model Pontiac, a new front brake pipe connector washer number 231343 must be installed to provide proper sealing.
1966 PONTIAC & TEMPEST LOW BRAKE PEDAL CHECK & ADJUSTMENT NOTE - If condition is encountered during brake application, measure pedal-to-toeboard clearance with carpet firmly pressed down in area of measurement. Maintain adjustment at or above low limit as follows:
| Pontiac | Tempest | |
|---|---|---|
| Std. Brakes | 5 1/8-5 3/8" | 5 5/8-5 7/8" |
| Power Brakes | 2 1/4-2 3/4" | 3 1/8-3 3/8" |
BUICK WHEEL BOLT REPLACEMENT NOTE - Wheel bolts on cast iron drums must not be pressed out. Drill out bolt and cut off head. To remove wheel bolts from aluminum drums, use suitable press.
BUICK BRAKE ROD FRONT & REAR BUSHING WASHER LOCATION - Under no circumstances should front and rear brake reaction rod bushing washers be relocated to a different position. This would cause toe in, caster and camber to be out of specifications.
1973 ELDORADO REAR BRAKE ADJUSTER PAWL REVISED - Eldorados incorporate (interim 1973) a revised automatic adjuster pawl. Change involves use of a separate blade to contact the adjuster star wheel. Blade is retained by means of a slot (similar to Fleetwood, Calais, DeVille). Use of this design also eliminates the override spring.
