Essential tech fitting tips for Range Rover and Land Rover handbrake shoes
Borg & Beck, parent company of First Line

First Line has updated its WebCat portal and released technical information about the handbrake shoes on the Range Rover Sport and Land Rover Discovery.

Both of these applications are fitted with electronic parking brake (EPB) modules, which control the handbrake shoe mechanism electronically via an actuator.

First Line say EPB problems will develop if the handbrake shoes are worn, in need of replacement, corroded, or more importantly, if the adjustment is not checked and set correctly.

Premature failure

An incorrect adjustment can cause the small teeth inside the unit to break or the small adjuster nut to over tighten and become jammed at its maximum travel.

First Line said: “If the vehicle is fitted with new rear brake discs or parking brake shoes, it is imperative that the parking brake shoe adjustment and bedding in procedures are carried out in full.

“Failure to do so may result in the premature failure of the EPB module, which is not a handbrake shoe fault.”

First Line also advises that every two years, or if the vehicle has been driven in muddy conditions for more than 50 miles, a full inspection of parking brake shoes is carried out.

It added: “If the vehicle is stationary and there is a screeching noise when applying or releasing the EPB, possibly with a parking sensor flashing on the dashboard, it’s likely that the EPB actuator needs replacing.

“In this instance, the EPB module has over travelled and become jammed, locking on the brakes and triggering the parking sensor to flash on the dashboard.

“This can happen as a result of the vehicle being driven with the handbrake applied, causing excessive lining wear, noise and heat build-up, ultimately damaging the rear braking system.

Identifying the problem

“Early stages of this problem can be identified when the vehicle is moving, if there is a screeching or rubbing noise coming from rear brakes and the EPB actuator is working fine, then a full inspection of the parking brake shoes will need to be carried out and corrected as soon as possible.

“If there is no screeching but there is shoe drag, then the technician will need to carry out an inspection and evaluate and fix problems caused by any heat damage.”

First Line’s individual guides for the inspection, adjustment and bedding in of brake shoes will be published on GW in the coming weeks.
