I have done Disc brake conversions on my 57 Olds. and my 64 Riviera.
Used Scarebird on both. No problem, brakes work great.
Also changed to duel master cyl, and booster.
See list of parts used for the 64 Rivera brake conversion below from Scarebird.
Read instructions thoroughly twice.
Crack front wheel nuts loose, chock up rear wheels. Jack up front end of car, support crossmember with jackstands. Remove front wheels and drum/hub assembly.
Disconnect brake flexible line at frame by spraying with penetrant oil, then unscrewing hardline nut with flare wrench, then removing clip. Undo lower drum backing plate nuts, and remove drum bolts. Remove drum backing plate and all drum hardware in one assembly. Clean off spindle assembly
Slip adapter plate down over spindle with caliper opening to the rear and machined pocket engaging spindle boss. Bracket will fit between spindle and steering arm.
Insert supplied top bolt and lock washer loosely, then reinsert lower bolts. Now torque upper bolt to 90 ft-lbs. and then torque lowers to 75 ft-lbs.
(1961-64 only) Drive out 14mm x 1.5 studs out of rotors, and press in Moser 8368 (1.75”) or 8250 (1.938”) or equivalent studs. NAPA also has 641-3204 (1-5/8”) or 641-1112 (1-15/16” use with ¼” wheel spacer only unless you chase the threads further down the stud). I usually lube up the splines and threads with anti-seize, then press (do not hammer) studs into place. Check to make sure studs are straight and fit inside wheel. 1965 Riviera will not need to change studs.
Clean and repack wheel bearings. Insert inner bearing into rotor, and install new seal. Assemble rotor onto spindle, along with bearing and washer, then tighten outer nut to spec, then secure with keeper, new cotter pin and new dustcap.
Wipe down rotor with alcohol, lacquer thinner or other cleaner to remove grease and oils.
Wash hands! Rotor must be squeaky clean
Test fit hoses on calipers. Note how hose kicks in towards caliper to clear sway bar. You may need to take an angle grinder to “flatten” the caliper where circled for clearance. Make sure clearance is visible – if it hangs up the hose will leak. Do not grind into sealing surface – be cautious and patient. Carefully remove rubber sleeve on hoses with knife. Hose should run straight down from caliper
Install loaded caliper with bleed screw facing up, and lube contact areas with silicone grease then screw in slide bolts, tighten to 35 foot-pounds. (1961-64 only) Note the third picture – the outer pads will contact the rotor slightly – a moment with a bench grinder will radius it enough to clear. (1965 Riviera should clear fine). We recommend using the softest pads you can find for street use, like NAPA’s TruStop organic. Pads are the same application as calipers. Check fitment and rotate rotor to check clearance.
Hoses should run down from caliper as shown in first illustration, then up to hardline, forming a “J”. Install new hoses with copper crush washers then reconnect to hard line. Some hardlines may have a 7/16” nut – if so, you will need to use NAPA #7828 adapter, or cut off flare, insert 3/8” nut then reflare. Master cylinder and proportioning valve specs are quite varied. I would recommend 1971-76 Riviera or similar disc master cylinder for best performance match available in both power and manual flavors. Some have used the existing single chamber master cylinder with success. If rear brakes lock up excessively, plumb in an adj. prop. valve in the line going to the rear.
Bench bleed disc master cylinder, mount on car. Gravity bleed first, then pressure/pump bleed entire system and test. You will need to reset the toe-in. Count number of threads per inch at the tie rod sleeve. Divide by 8. This is the number of turns your sleeve needs to be spun to shorten the distance to make up for the thickness of the bracket.
Replace wheels, torque wheel nuts, lower car and carefully test. We use the 30-30-30 method to break in pads: 30 easy stops from 30mph with 30 seconds cooling between stops. Then let cool ½ hour.
