What the manufacturer’s document says

00-05-22-002N ・ fault and correction ・ for GM vehicles in general

Applies to

  • Applies to 2014 and prior GM passenger cars and light duty trucks.

    the passage
    2014 and Prior GM Passenger Cars and Light Duty Trucks

Finding the cause

Possible causes

  • Brake pulsation is caused by brake rotor thickness variation.

    the passage
    Brake pulsation is caused by brake rotor thickness variation.

  • If the brake corner is assembled with excessive lateral run out (greater than 0.050 mm (0.002 in)), thickness variation develops on the rotor over time and miles.

    the passage
    is assembled with excessive LRO (greater than 0.050 mm (0.002 in), thickness variation will develop on the brake rotor over time and miles.

  • Pulsation from excessive lateral run out usually develops in 4,800-16,000 km (3,000-10,000 mi).

    the passage
    Lateral Run Out usually develops in 4,800-16,000 km (3,000-10,000 mi).

  • Lateral run out can also be induced when uneven torque is applied to the wheel nuts.

    the passage
    can also be induced when uneven torque is applied to wheel nuts (lug nuts).

Steps to confirm (in the document’s order)

  • If the lateral run out (LRO) measurement is 0.050 mm (0.002 in) or less, no correction is necessary.

    the passage
    If the Lateral Run Out (LRO) measurement is 0.050 mm (0.002 in) or LESS, no correction is necessary.

Correction

Repair

  1. Clean all mating surfaces between the hub, the rotor and the wheel using the J 42450A Wheel Hub Cleaning Kit and J 41013 Whiz Wheel.

    the passage
    Clean all of the mating surfaces between the hub, the rotor and the wheel using the J 42450A – Wheel Hub Cleaning Kit and J 41013 – Whiz Wheel®.

  2. After refinishing, sand both sides of the rotor for about one minute per side with a sanding block and 130-150 grit sandpaper to obtain a non-directional finish.

    the passage
    After completing the refinish, sand both sides of the rotor for approximately one minute per side using a sanding block and 130-150 grit sandpaper to obtain a non-directional finish.

  3. Corrosion-related pulsation at low miles can be cleaned up (burnished) by 10 - 15 moderate stops from 56 - 64 km/h (35 - 40 mph) with cooling time between stops.

    the passage
    Cleaning up of braking surfaces (burnishing) can be accomplished by 10 – 15 moderate stops from 56– 64 km/h (35 – 40 mph) with cooling time between stops.

  4. For brake noise, verify that all metal-to-metal contact areas between pads, pad guides, caliper and knuckles are clean and lubricated with a thin layer of high temperature silicone grease.

    the passage
    areas between pads, pad guides, caliper and knuckles are clean and lubricated with a thin layer of high temperature silicone grease.

Parts

  • Silicone Brake Lubricant: ACDelco P/N 88862182 (Canadian P/N 88862496) or equivalent.

    the passage
    Use Silicone Brake Lubricant, ACDelco P/N 88862182 (Canadian P/N 88862496) or equivalent.

Part numbers printed in the document

The numbers are as the document prints them. The name and the replacing number are what the pages of GMPartsGiant, a reseller of genuine parts and not GM, state. Aftermarket equivalents are not checked here (the links only search by number). Confirm the fit for the vehicle (VIN) before ordering.

Caution

  • For routine service for worn pads only, if the rotors are not damaged and measure within specification, do not refinish the rotors.

    the passage
    If performing routine Brake Service for worn pads only, and the rotors are not damaged and measure within specification – DO NOT REFINISH ROTORS.
