>> A << Rear Brake Assembly Installation

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

In order to measure brake drag torque after pad installation, measure hub torque with the pads removed.
Use a spring scale to measure hub torque in the direction shown. Record the value.

CAUTION: Do not let any oil, grease or other contamination get onto the friction surfaces of the pads and brake discs.
After re-installing the caliper support, install the pad clips and pads to the caliper support.
Clean the piston and insert it into the cylinder with special tool MB990520.
Be careful that the piston boot does not become caught, when lowering the caliper assembly and installing the guide pin.
Check brake drag force as follows:
1. Start the engine and hold the brake pedal down for five seconds. [Pedal depression force: approximately 196 N (44 pound)]

2. Stop the engine.
3. Turn the brake disc forward ten times.
4. Use a spring scale to measure the hub torque with pads installed in the same direction as earlier.
5. Calculate the drag force of the disc brake [difference between hub torque with pads installed and hub torque with pads removed].
  Standard value: 69 N (16 pound) or less
If the drag torque exceeds the standard value, disassemble and clean the piston. Check for corrosion or worn piston seal, and check the sliding condition of the lock pin and guide pin.
