How Sturdy Are Caliper Pins?
#11
I'm getting the feeling here that some of you think the pins are involved in the force of stopping of the vehicle, such that they can make noise when brakes are applied. All they do is let the single piston caliper slide sideways. There is no real force on them at all, ever. The force is all on the pads and knuckle. I know this sounds like a grade school answer, but as I said, from the above prose, I'm not sure everyone is on the right page.

•Steering wheel and seat vibration (in extreme conditions)
NOTE: NO REDUCTION IN BRAKING ABILITY OR PARTICULAR DAMAGE TO THE BRAKE SYSTEM WILL RESULT FROM THESE NOISES.
DIAGNOSIS:
1.Drive the vehicle on a smooth surfaced road in an area away from heavy traffic and high surrounding noise.
2.Make several stops from a moderate speed to generate some heat within the brake system.
3.Accelerate to 15 - 20 mph (24 - 32 kph), then apply moderate pressure to the brake pedal until the vehicle comes to a stop.
4.If a grinding/growling noise is coming from the front brakes, perform the Repair Procedure. If there is no noise, drive the vehicle for several miles (kilometers) with minimal brake applications to allow the brake system to cool or park the vehicle until the brakes cool, then repeat Steps 2 and 3 again. If the grinding/growling noise is now coming from the front brakes, perform the Repair Procedure.

REPAIR PROCEDURE:
This bulletin involves installing a revised set of front brake shoes.
1.Clean master cylinder reservoir and filler caps.
2.Remove the reservoir filler cap and remove approximately 1/4 of the fluid from the reservoir. Use aclean suction gun or similar device to drain the brake fluid.
3.Raise and support the vehicle.
4.Remove front wheel and tire assemblies.
1.Bottom the caliper pistons in the caliper bores using a large C-clamp. Position the C-clamp frame on the rear of the caliper and clamp screw on the outboard brake shoe.
5.Remove the caliper slide pins.
6.Remove caliper from caliper adapter.
CAUTION: DO NOT ALLOW THE CALIPER TO HANG BY THE BRAKE HOSE. USE A HANGER TO SUPPORT THE CALIPER WHILE SERVICING THE BRAKE SHOES.
7.Remove the outboard brake shoe (Figure 1). Pry one end of the shoe retainer spring away from the caliper, then tilt the shoe upward and rotate it out of the caliper.
8.Remove the inboard brake shoe by tilting the shoe outward until the retainer spring is clear of the caliper piston (Figure 2).
9.Remove any dirt or foreign material from the wear surface of the rotor.
10.Secure a dial indicator onto the steering knuckle so that the plunger of the dial indicator is positioned approximately 25.4 mm (1 in.) inward from the rotor’s edge (Figure 3). If the runout exceeds 0.102 mm (0.004 in.), replace the rotor with p/n 52009208 . Refer to the 1999 Durango Service Manual (Publication No. 81-370-9116), page 5-16 for information regarding rotor replacement.
11.Position a micrometer approximately 25.4 mm (1 in.) from the rotor outer circumference (Figure 4) and measure the rotor thickness. Take an additional 6 - 12 measurements around the rotor. If the thickness of the rotor varies more than 0.013 mm (0.0005 in.) from point to point, replace the rotor with p/n 52009208. Refer to the 1999 Durango Service Manual (Publication No. 81-370-9116), page 5-16 for information regarding rotor replacement.
12.Install inboard brake shoe from brake shoe kit p/n 05014095AB. Be sure the retainer spring is firmly seated in the caliper piston.
13.Insert outboard brake shoe into the caliper (Figure 5).
14.Ensure the outboard brake shoe retainer springs are seated in the caliper (Figure 6).
15.Install caliper and brake shoe assembly over the rotor and into the adapter. Be sure the brake shoe tangs are properly seated on the adapter ledges.
16.Install and tighten the caliper slide pins to 25 - 35 N•m (18 - 26 ft. lbs.).
NOTE: START THE SLIDE PINS BY HAND BEFORE TIGHTENING. DO NOT CROSS THREAD THE PINS.
17.Perform Step 5 through Step 17 to the front brakes on the other side of the vehicle.
18.Install the wheel and tire assembly.
19.Remove supports and lower the vehicle.
20.Pump the brake pedal several times to seat the new brake shoes.
CAUTION: VERIFY A FIRM BRAKE PEDAL BEFORE MOVING THE VEHICLE.
21.Ensure that the master cylinder reservoir is at the proper level as indicated on the side of the reservoir. Fill the reservoir with Mopar Brake Fluid p/n 04318080.
22.Repeat the Diagnosis to ensure that the brake growl/grind noise has been eliminated.
