  • 1. 2000-01 BRAKES Disc & Drum - Trucks - Except Tracker MODEL IDENTIFICATION Vehicle model can be identified by fifth character of Vehicle Identification Number (VIN), stamped on metal pad on top of left end of instrument panel, near windshield. See MODEL IDENTIFICATION table. MODEL IDENTIFICATION DESCRIPTION & OPERATION BRAKE SHOE ASSEMBLY Some "U" series vehicles are equipped with leading/trailing brakes, identified by adjuster screw hole in backing plate, located above horizontal centerline of rear axle. All other models are equipped with dual-servo brakes, identified by adjuster screw hole at bottom of backing plate. Brake assembly consists of backing plate, brake shoes, return springs, automatic adjusting assembly and a wheel cylinder. Automatic adjusting assembly consists of an actuator lever, return spring, actuator link, adjusting screw and spring. Automatic adjustment is accomplished through movement of actuating lever and secondary shoe. BRAKE WARNING LIGHT Aztek Series (1) Model "A" 2WD Aztek "B" 4WD Aztek "C" Silverado, Sierra, Suburban, Tahoe & Yukon "G" Express & Savana "K" Escalade, Silverado, Sierra, Suburban, Tahoe & Yukon "L" AWD Astro & Safari "M" 2WD Astro & Safari "S" 2WD Blazer, Envoy, Jimmy, S10 & Sonoma "T" 4WD Blazer, Bravada, Envoy, Jimmy, S10 & Sonoma "U" Silhouette, Montana & Venture (1) Vehicle series is fifth character of VIN.

  • 2. Brake warning light is energized when ignition is on and parking brake is applied. If brake fluid level is low, a low brake fluid level indicator is displayed on message center. Montana, Silhouette & Venture Brake warning light is energized when ignition is on and parking brake is applied, or when master cylinder fluid level is low. Brake warning light is not energized if hydraulic pressure is lost; system is not equipped with pressure differential switch. Except Aztek, Montana, Silhouette & Venture Pressure differential warning switch in combination valve energizes brake warning light on instrument panel when front or rear brakes lose hydraulic pressure. After repairing failed side of hydraulic system, depress brake pedal with moderate to heavy pressure to hydraulically center the piston. This will turn off brake warning light. On vehicles with Hydro-Boost, insufficient flow of power steering fluid to the hydraulic booster system will turn on brake warning light. CALIPERS Front brakes are single piston caliper or dual piston caliper design. See Fig. 11 and Fig. 12 . Rear brakes are sliding caliper design. Caliper is attached to caliper mount. Caliper is mounted to steering knuckle or caliper adapter, depending on application. Caliper assembly slides back and forth in machined cutouts. HYDRAULIC CONTROL VALVES Dynamic Rear Proportioning (Aztek) Dynamic Rear Proportioning (DRP) is a control system that replaces hydraulic proportioning function of mechanical proportioning valve in base brake system. DRP control system is part of operation software in EBCM. DRP uses active control with existing ABS in order to regulate vehicle's rear brake pressure. Combination Valve (Except Aztek, Montana, Silhouette & Venture) System uses a combination valve to regulate brake system hydraulic pressure. Combination valve, located in brake lines between master cylinder and wheels, has 3 pressure control functions:  Metering (or hold-off) section of valve limits pressure to front brakes until pressure of rear brake shoe retractor springs is overcome, then allows pressure to front brakes.  Warning switch section of valve constantly compares front and rear brake pressures from master cylinder. See BRAKE WARNING LIGHT under DESCRIPTION & OPERATION.  Proportioning section of valve allows input pressure to rise to predetermined level before allowing output pressure to rear brakes. This prevents rear wheel lock-up on vehicles with light rear wheel loads. Combination valve also contains a by-pass feature. This ensures full system pressure is applied to rear brakes if front brakes lose hydraulic pressure (or if rear brakes lose hydraulic pressure, full pressure is applied to front brakes). 2001 Oldsmobile Bravada 2000-01 BRAKES Disc & Drum - Trucks - Except Tracker Microsoft Thursday, April 22, 2010 9:29:43 AM Page 2 © 2006 Mitchell Repair Information Company, LLC.
  • 3. Proportioning Valves (Montana, Silhouette & Venture) System uses 2 proportioning valves, threaded into master cylinder, to regulate brake system hydraulic pressure. Valves allow input pressure to rise to predetermined level before allowing output pressure to rear brakes. This prevents rear wheel lock-up on vehicles with light rear wheel loads. Valves also incorporate a by-pass feature which ensures full system pressure is applied to rear brakes if front brakes lose hydraulic pressure (or if rear brakes lose hydraulic pressure, full pressure is applied to front brakes). BLEEDING BRAKE SYSTEM MASTER CYLINDER BLEEDING 1. Place master cylinder in soft-jaw vise with front end tilted slightly down. DO NOT overtighten vise. Plug both outlet ports of master cylinder. Fill master cylinder reservoir. 2. Press and release piston about 1" (25 mm) several times. As air is bled from master cylinder, the primary piston will not travel the full 1" (25 mm) stroke. 3. Repeat previous step with front end of master cylinder tilted slightly up. Reposition master cylinder in vise to level position. Loosen front outlet plug and push piston into bore to expel air from cylinder. Tighten plug and allow piston to return to original position. Repeat procedure at rear outlet plug. 4. Fill reservoir and install master cylinder. DO NOT fully tighten brake lines at this time. Slowly press brake pedal to floor and hold. Tighten brake lines. Release brake pedal. Bleed brake system. See MANUAL BLEEDING or PRESSURE BLEEDING . MANUAL BLEEDING 1. Deplete vacuum reserve from power brake booster by depressing brake pedal several times with engine off. Fill master cylinder and keep at least three quarters 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. Have an assistant depress brake pedal slowly and NOTE: The following bleeding procedures apply to all vehicles except model year 2000 Montana, Silhouette and Venture FWD vans. Manufacturer recommends using Tech 1 bleeding procedure. See ANTI-LOCK - FWD VAN article. On vehicles with Hydro-Boost, check for air bubbles in power steering fluid reservoir. If air bubbles are present, bleed Hydro-Boost system before bleeding brake system. See POWER BRAKE BOOSTER - BENDIX HYDRO-BOOST article. NOTE: To prevent air from entering brake system, bench bleed master cylinder before installing. NOTE: Air tends to cling to caliper walls. When bleeding vehicles with disc brakes, lightly tap caliper to help remove air. 2001 Oldsmobile Bravada 2000-01 BRAKES Disc & Drum - Trucks - Except Tracker Microsoft Thursday, April 22, 2010 9:29:43 AM Page 3 © 2006 Mitchell Repair Information Company, LLC.
  • 4. hold. Loosen forward fitting. Tighten fitting while pedal is still at floor. Release brake pedal slowly. Wait 15 seconds. 3. Repeat step 2, including 15 second wait, 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 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 right rear wheel. Place proper size box end wrench over bleeder valve. Attach one end of clear tube over valve and submerge other end in container partially filled with clean brake fluid. 5. Have an assistant depress brake pedal slowly and hold. Loosen bleeder valve to purge air from cylinder. Tighten bleeder valve and slowly release brake pedal. Wait 15 seconds. Repeat sequence, including 15 second wait, until all air is removed. 6. Remove tube and wrench. Repeat step 5 at left rear, right front, and left front wheels in this order. Fill master cylinder reservoir, and install cover. Ensure there is no sponginess in brake pedal and that BRAKE warning light is off. PRESSURE BLEEDING 1. Clean master cylinder cap and surrounding area. Remove cap. Install Brake Pressure Bleeder Adapter (J- 35589-A) onto master cylinder reservoir. With pressure tank at least 2/3 full, connect pressure bleeder to master cylinder with adapters. Attach bleeder hose to right rear bleeder valve. 2. Place other end of hose in glass jar partially filled with brake fluid so end of hose is submerged in fluid. Open release valve on pressure bleeder. Set pressure bleeder to 25-30 psi (1.75-2.11 kg/cm2 ) or pressure specified by equipment manufacturer. 3. Open bleeder screw 3/4 - 1 turn and note fluid flow. Close bleeder screw when no air bubbles are present NOTE: Rapid pumping of brake pedal causes master cylinder secondary piston to move into a position that makes bleeding system difficult. NOTE: On vehicles with 4WAL, if brake pressure modulator valve was replaced, or is suspected to have air trapped inside, it must be bled next. See appropriate ANTI-LOCK article. NOTE: Air tends to cling to caliper walls. When bleeding vehicles with disc brakes, lightly tap caliper to help remove air. WARNING: Do not use rigid clamp to position hold-off valve stem. This may damage valve assembly, causing brake failure. NOTE: On vehicles with 4WAL, if brake pressure modulator valve was replaced, or is suspected to have air trapped inside, it must be bled next. See appropriate ANTI-LOCK article. 2001 Oldsmobile Bravada 2000-01 BRAKES Disc & Drum - Trucks - Except Tracker Microsoft Thursday, April 22, 2010 9:29:43 AM Page 4 © 2006 Mitchell Repair Information Company, LLC.
