1999 Dodge Caravan 1999 Dodge Grand Caravan soft brake peda

1999 Dodge Caravan 123000 miles

I changed the brake pads, and bled the brake lines on my 1999 Dodge Caravan yesterday. I now have a very soft pedal that slowly sinks to the floor. This is my wife's daily driver, and she thinks she can hear a "whooshing" noise whenever she brakes. Any help would be great.
Do you
have the same problem?

When you replaced the pads, and you pushed the pistons back, did you loosen the cap on the Master first? Will pedal sink to floor? Light on dash come on? And if you didnt change the calipers, why did you bleed it? This is a diagonal brake system, meaning the rr and lf are paired off the master and lr rf are paired, bleed at the rear and at hieght sensing valve if it has one, do it on level ground, with wheels on the ground.


HEIGHT-SENSING PROPORTIONING VALVE Models Without ABS 1. Raise and support vehicle. Remove rear wheels. Support rear axle with jack. Unbolt both rear shock absorbers from rear axle. 2. Unbolt track bar from rear axle. Track bar fits between top of rear axle and body. Loosen leaf spring-to-front spring hanger pivot bolts. DO NOT remove pivot bolts. 3. Lower rear axle fully downward. Ensure rear axle moves freely fully downward and does not contact any service equipment. Loosen valve adjustment nut on valve actuator at height-sensing proportioning valve. See Fig. 1 . Height-sensing proportioning valve is located on outside of driver's side frame rail, in front of rear axle. 4. Ensure hooked end of valve actuator is fully seated in clip on lever of height-sensing proportioning valve. Ensure clip is correctly positioned on lever of height-sensing proportioning valve. 5. Pull valve actuator housing toward front of vehicle until lever on height-sensing proportioning valve bottoms on height-sensing proportioning valve. See Fig. 1 . 6. Hold valve actuator housing in this position while tightening valve adjustment nut to specification. See TORQUE SPECIFICATIONS table. Reinstall shock absorbers and track bar on rear axle with bolts/nuts loosely installed. DO NOT tighten bolts/nuts at this time. 7. Install rear wheels. Tighten lug nuts to specification. See TORQUE SPECIFICATIONS table. Lower vehicle to normal operating position with all vehicle weight on suspension. NOTE: Height sensing proportioning valve adjustment will be required if a premature rear wheel lock-up exists and all brake linings are okay, height-sensing proportioning valve is replaced or if a complaint of a hard brake pedal effort exists with proper operation of power brake booster. CAUTION: Aftermarket load leveling devices such as air shock absorbers or helper springs MUST NOT be used on models with height-sensing proportioning valve. Using load leveling devices will cause height- sensing proportioning valve to reduce hydraulic pressure to rear brakes which may result in increased stopping distance. NOTE: When lowering rear axle, ensure leaf springs DO NOT contact any service equipment such as hoist. Rear axle must move freely downward to extent of its normal travel. If rear axle contacts any service equipment, improper adjustment of height-sensing proportioning valve will result. CAUTION: Vehicle must be in normal operating position with all vehicle weight on suspension system before tightening shock absorbers, track bar and leaf spring-to-front spring hanger pivot bolts to specification.
8. Tighten leaf spring-to-front spring hanger pivot bolts, shock absorber-to-rear axle bolt and track bar-to-rear axle bolt to specification. See TORQUE SPECIFICATIONS table. Road test vehicle to ensure proper brake operation.
ABS BLEEDING 1. Ensure all hydraulic brake system components are properly installed and all connections are tight. Using scan tool, check Controller Anti-Lock Brake (CAB) for faults. If any faults are stored, clear CAB faults. 2. Bleed base brake system. See MANUAL BLEEDING or PRESSURE BLEEDING . After bleeding base brake system, using scan tool, select ANTI-LOCK BRAKES followed by MISCELLANEOUS, then BLEED BRAKES. Follow scan tool screen prompts. When scan tool displays TEST COMPLETED, disconnect scan tool. Bleed base brake system again. Top off brake fluid reservoir and verify proper brake operation before moving vehicle. NOTE: Diagnostic Readout Box (DRB-III) is necessary to properly bleed Teves Mark 20 anti-lock brake system. Page 1 of 1 ANTI-LOCK - TEVES MARK 20 -1999 Dodge Caravan 4/20/2009
