Record by record

11 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

      What the documents say to do

      Brake pipe (brake line) corrosion and rupture

      Confirm

      • In the joint inspections, scaling or flaking corrosion was taken as indicating the onset of metal loss and given the second lowest ranking (2); a leaking or previously repaired pipe was the lowest (1).

      Repair

      1. GM recommends replacing the entire set of pipes whenever any pipe leaks or is corroded enough to need replacement.
      2. On June 28, 2013 GM released 66 new part numbers for servicing brake pipes in 1999-2007 GMT800 pickups and utility vehicles.

      Caution

      • Analysis of repair records indicates that consumers often elect to repair only the failed circuit.

Known issuesUnwanted ABS activation at low speed (front wheel speed sensor mounting corrosion)1

  1. Owner complaint2001 GMC YUKON XL ・ 2004-07-16

    Anti-lock brake system pulsates and groans at low speed braking

    1. 1Fault

    2. 2Finding the cause

    3. 3CorrectionNot repaired

      VEHICLE WAS NOT REPAIRED AT THIS TIME, FEELING THERE IS A SAFETY ISSUE WITH THE HUB ASSEMBY AND REPLACING OTHER PARTS ARE NOT TOTALLY NECESSARY. *AK

      What the documents say to do

      Unwanted ABS activation at low speed (front wheel speed sensor mounting corrosion)

      Confirm

      • The reading should be at least 350 mV AC; if it is less, the wheel speed sensor must be replaced.

      Repair

      1. Dealers remove the sensor, clean its mounting surface on the bearing, apply rust inhibitor and grease, reinstall it and check peak-to-peak output voltage.
      2. The passage heading states that the repair is cleaning the wheel speed sensor mounting surface.

      Caution

      • Do not pry the sensor out of the bore; prying breaks the sensor body off in the bore.

Known issuesParking brake linings worn out prematurely, parking brake does not hold (PBR single-shoe drum-in-hat)1

  1. Owner complaint2001 GMC YUKON XL ・ 2004-09-15

    Parking brake does not hold vehicle when applied

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

      What the documents say to do

      Parking brake linings worn out prematurely, parking brake does not hold (PBR single-shoe drum-in-hat)

      Confirm

      • On complaint vehicles examined in the field, wear occurred earlier and to a greater extent on the driver's side parking brake unit and was largely localized at the tip of one of the linings.

      Repair

      1. A revised clip designed to exert less force on the shoe went into MY 2003 production and into the service part stream. Installing the newer clip and replacing worn linings has been shown to remedy the defect.
      2. The closing report lists a bulletin of Aug 2004 as 02-05-26-001B "Brakes - Parking Brake Shoe Retainer Clip Availability", announcing a new retainer clip service kit for DIH-equipped vehicles.

      Caution

      • The vehicles warn the operator with a chime if driven over 3 mph (= 4.83 km/h) with the parking brake engaged.
