Disc & Drum Brake System Buick Roadmaster VIII

DESCRIPTION & OPERATION

Hydraulic system pressure differential is controlled and monitored by combination valve, located below master cylinder (attached to ABS modulator on Camaro and Firebird). Combination valve performs the following functions

1. Limits amount of pressure applied to rear brakes to allow most pressure to be applied to front brakes.
2. Transfers hydraulic pressure to front brakes if pressure loss occurs in rear brakes and vice versa.
3. Closes contacts in pressure differential switch to turn on BRAKE warning indicator light.
4. On Fleetwood, Caprice and Roadmaster, metering valve portion of combination valve prevents hydraulic pressure from being applied to front brakes until rear brakeline pressure has overcome rear brake shoe return spring tension, and brake shoe-to-drum clearance has been taken up.

Disc brakes are continually self-adjusting. Caliper piston seals are designed to retract pistons enough to allow brake lining to lightly brush rotor. Sliding caliper design compensates for lining wear.

BRAKE WARNING INDICATOR INOPERATIVE

See appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT.

BLEEDING BRAKE SYSTEM

MANUAL BLEEDING

Note. On Fleetwood, bleed ABS modulator if master cylinder reservoir fluid level was low during traction control mode or if ABS modulator was removed and installed.

ABS Modulator (Fleetwood)

Fill brake fluid reservoir. Keep reservoir at least half full during procedure. Attach clear hose to bleeder valve on ABS modulator. (Scheme 1) Submerge hose end in clear container partially filled with brake fluid. Open bleeder valve. Allow fluid to drain until air bubbles cannot be seen in fluid. Close bleeder valve. Remove hose.

Scheme 1

Note. For brake system bleeding on Camaro and Firebird, see appropriate ANTI-LOCK BRAKE SYSTEM article.

Brake System (Caprice, Fleetwood and Roadmaster)

1. Deplete vacuum reserve from power brake booster by depressing brake pedal several times with engine off. Fill master cylinder and keep at least half full during bleeding procedure. If master cylinder is not known or suspected to have air in bore, go to step 4). If master cylinder is known or suspected to have air in bore, go to next step.
2. Disconnect forward brakeline fitting at master cylinder. Allow fluid to flow from fitting. Tighten fitting to specification. See TORQUE SPECIFICATIONS table at the end of this article. Have an assistant depress brake pedal slowly and hold. Loosen forward fitting. Tighten fitting while pedal is still at floor. Release brake pedal slowly. Wait 15 seconds.
3. Repeat step 2) until fluid is clear and free of air bubbles. Repeat procedure at other (rearmost) brakeline fitting on master cylinder. Master cylinder is now bled. If wheel cylinders/calipers are not known or suspected to have air in them, it is not necessary to bleed them.
4. If wheel cylinders/calipers are known or suspected to have air in them, raise and support vehicle. Remove bleeder valve cap from first bleeder valve to be serviced. See BRAKELINE BLEEDING SEQUENCE table. Place wrench over bleeder valve.
5. Attach clear vinyl bleeder hose onto bleeder valve. Place other end of hose in clear container partially filled with clean brake fluid. Submerge end of hose in fluid. Open bleeder valve 1-2 turns. Slowly depress brake pedal to floor.
6. Close bleeder valve. Release pedal. Pump pedal several times to push air toward wheel cylinder/caliper. Wait 15 seconds and repeat procedure until fluid is clear and free of air bubbles. Repeat procedure on remaining bleeder valves.

BRAKELINE BLEEDING SEQUENCE

PRESSURE BLEEDING

Note. For brake system bleeding on Camaro and Firebird, see appropriate ANTI-LOCK BRAKE SYSTEM article.

1. Clean master cylinder reservoir cap and surrounding area. Remove cap. With pressure bleeder tank at least 1/2 full of brake fluid and charged with 10-30 psi (.70-2.10 kg/cm 2 ) air pressure, connect tank to master cylinder using proper adapter(s).
2. On vehicles with rear disc brakes, go to next step. On vehicles with rear drum brakes, a manual override is necessary to permit brake fluid flow to front wheels when pressure bleeding. To enable override, attach Combination Valve Pressure Bleeder Adaptor (J-39177) to combination valve.
3. Raise and support vehicle. Attach bleeder hose to first bleeder valve to be serviced. See BRAKELINE BLEEDING SEQUENCE table under MANUAL BLEEDING. Place other end of hose in clear container partially filled with clean brake fluid. Submerge end of hose in fluid.
4. Open release valve on pressure bleeder. Open first bleeder valve to be serviced. When fluid flowing into container is clear and free of bubbles, close bleeder valve securely. Open and close each remaining bleeder valve in turn to finish bleeding system. Disconnect pressure tank from master cylinder. Remove adaptor from combination valve. Check brake fluid level. Fill as necessary.

REAR BRAKE SHOES

Note. Adjustment is only required if shoes have been serviced or length of adjusting screw has been changed.

1. Release parking brake. Raise and support vehicle. Remove wheels and drums. Ensure parking brake cable, linkage and secondary (rear) shoe levers have free movement.
2. If using Brake Drum Gauge (J-21177), go to next step. If not using Brake Drum Gauge (J-21177), turn adjuster wheel until diameter of brake shoes is .050" (1.27 mm) less than inside diameter of brake drum. Go to step 4).
3. Measure inside diameter of brake drum using inside caliper portion of Brake Drum Gauge (J-21177). Turn adjuster wheel until brake shoes contact outside caliper portion of brake drum gauge.
4. Install drums and wheels. Tighten wheel lug nuts to specification. See TORQUE SPECIFICATIONS table at the end of this article. Lower vehicle. Drive vehicle, making several alternate forward and backward stops, applying brakes firmly.

Preliminary Information (Camaro and Firebird)

1. Adjustment is normally required only if caliper has been disassembled or pads have been replaced. Ensure brake pads are NEW or parallel to within.006" (.15 mm) thickness. Adjustment will not be accurate if pads are heavily tapered.
2. Turning adjusting screw clockwise increases free play. (Scheme 2) Turning adjusting screw counterclockwise decreases free play. Adjustment will not correct a condition such as levers not returning to their stops.

Adjustment (Camaro and Firebird)

1. Disconnect cable end from parking brake lever on caliper. (Scheme 2) Remove lever return spring. Have an assistant apply and hold light pressure on brake pedal (enough to stop rotor from turning by hand). This takes up clearances and ensures components are aligned.
2. Apply light hand pressure to parking brake lever. Check free play between lever and caliper stop. If free play is not.024-.028" (.60 -.70 mm), go to next step. If free play is.024-.028" (.60 -.70 mm), parking brake cable is adjusted. Install lever return spring. Reconnect parking brake cable.
3. Remove adjusting screw. Clean threads. Coat threads with adhesive. Install adjusting screw. Turn screw until free play between lever and caliper stop is.024-.028" (.60 -.70 mm). Have assistant release brake pedal, then apply brake pedal firmly 3 times. Recheck free play. Adjust again if necessary. Install lever return spring. Reconnect parking brake cable.

Scheme 2
