Record by record

140 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.

Component named as the cause

Work done

How it is said to have ended

  • says it was fixed1
  • says it came back2
  • result not stated45

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.

    Front Right Brake Pipe Clearance Recall

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

    Read the sentences of the record
    Cause
    VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND SPORT UTILITY VEHICLES. SOME OF THESE VEHICLES HAVE A CLEARANCE CONDITION BETWEEN THE FRONT RIGHT-HAND BRAKE PIPE AND THE BODY CROSS SILL THAT COULD DECREASE TO THE POINT OF ALLOWING CONTACT DURING THE LIFE OF THE VEHICLE. IF CONTACT OCCURS AND THE BRAKE PIPE BECOMES DAMAGED, IN HALF OF THE BRAKE SYSTEM THERE CAN BE A LOSS OF BRAKE FLUID AND PRESSURE. THE BRAKE WARNING LAMP WILL BE ACTIVATED WHEN THE BRAKE FLUID LEVEL REACHES THE INDICATOR LIMIT.
    Remedy
    DEALERS WILL INSPECT THE FRONT RIGHT-HAND BRAKE PIPE FOR WEAR. IF THERE ARE SIGNS OF WEAR, THIS SECTION OF THE BRAKE PIPE WILL BE REPLACED WITH A NEW DESIGNED BRAKE PIPE SECTION. IF THERE ARE NOT SIGNS OF WEAR ON THE BRAKE PIPE, THE DEALER WILL INSTALL A SPACER CLIP TO ENSURE SUFFICIENT CLEARANCE BETWEEN THE BRAKE PIPE AND THE BODY CROSS SILL.
    Consequence
    DURING BRAKING, THE PEDAL WILL BE LOWER THAN NORMAL AND STOPPING DISTANCES WILL BE LONGER. IF THIS OCCURS WHEN STOPPING DISTANCE IS LIMITED, A CRASH COULD OCCUR.

    Brake pipe wear contact recall

    1. 1Fault

    2. 2Finding the cause

    3. 3Correction

      Not stated

    Read the sentences of the record
    Cause
    On certain vehicles, the body cross sill may contact the front, right-hand brake pipe. This could eventually wear a hole in the brake pipe over the normal life of the vehicle and result in a brake fluid leak. This could ultimately result in a partial brake system failure and increased stopping distances. Correction: Dealers will inspect for brake pipe wear and replace worn section if necessary. A spacer clip will be installed to ensure adequate clearance.
