Brakes - Vibration/Pulsation Felt in Steering Wheel
NUMBER: 05-002-05GROUP: Brakes
DATE: January 29, 2005
SUBJECT:
Pulsation Or Vibration In The Brake Pedal and/or Steering Wheel
OVERVIEW:
This bulletin involves replacing the brake rotors instead of resurfacing.
MODELS:
2005 RS Town & Country/Caravan
NOTE:
This bulletin applies to vehicles equipped with disc/drum brakes (sales code BRB), built on July 1, 2004 through and including September 30, 2004 (MDH 0701XX through and including 0930XX).
DISCUSSION:
The vehicle may exhibit pulsation or vibration in the brake pedal and/or steering wheel when the brakes are applied. This condition is most noticeable at speeds greater than 30 MPH. The original equipment rotors on these vehicles cannot be corrected by resurfacing. If the owner describes this condition and if the vehicle is built with a disc/drum system (sales code BRB) between July 1, 2004 through and including September 30, 2004, perform the Repair Procedure. The old rotors are to be returned, in the box, through the normal warranty return process.
PARTS REQUIRED:
REPAIR PROCEDURE:
1. Raise vehicle on a suitable hoist.
2. Remove the front wheel and tire assembly.
3. Remove the two mounting bolts securing the disc brake caliper adapter with brake caliper to the steering knuckle (Fig. 1).
4. Remove the disc brake caliper and adapter as an assembly from the steering knuckle. Hang the assembly out of the way using wire or a bungee cord. Use care not to overextend the brake hose when doing this (Fig. 1).
5. Remove any retainer clips from the wheel mounting studs.
6. Remove brake rotor from hub by pulling it straight off the wheel mounting studs.
NOTE:
Step # 7 is to be performed through June 30, 2005. After that date proceed to Step # 8.
7. Place a tag on the rotor with the following information: the last eight characters of the VIN, vehicle mileage, and location on the vehicle (ie. Right Front = RF or Left Front = LF). Place the old rotor in the box that the new rotor was in.
8. Install the new brake rotor, p/n 05019981AA, on the hub and bearing.
9. Install the brake caliper and adapter back over brake rotor aligning the adapter with mounting holes on the steering knuckle (Fig. 1).
10. Install the two adapter mounting bolts securing the adapter to the steering knuckle. Tighten the mounting bolts to 169 N.m (125 ft.lbs.) torque.
11. Install the wheel and tire assembly on the vehicle. Tighten the wheel mounting lug nuts in proper sequence until all nuts are torqued to half specification, then repeat the tightening sequence to the full specified torque of 135 N.m (100 ft.lbs.) (Fig. 2).
12. Repeat Step # 2 through Step # 12 on the opposite side of the vehicle. When both front rotors have been replaced, proceed to Step # 13.
13. Lower vehicle to the ground.
14. Pump the brake pedal several times. This will set the pads to the brake rotor.
