I love reading your magazine and can’t wait for my monthly issue of Land Rover AFRICA Magazine. The handbrake of my Discovery 3 screeches when activated. I have heard of some horrific stories about handbrakes going into lock mode when off-roading. Is there any way that I can service this unit?
- Leon Joffee Ed – To be on the safe side, you should strip, inspect, and clean the electronic brake pads (EBP) after every off-road trip. The EPB is operated by a pair of brake shoes inside the rear brake discs. In my opinion, this is a similar system that is used on the Land Cruiser Station Wagon, which is essentially rubbish. First the EBP should be put into service mode. With the ignition in position, II press the brake pedal three times and hold pedal down. Push down the EBP switch for 3 - 5 seconds. Go to the main fuse box and remove FL8 fuse (pink fuse). Jack up the rear of the vehicle and place on sturdy stands. Remove both rear wheels. Do not apply the hand brake on your auto. The EPB can be adjusted through an inspection hole in the brake disc, but before adjusting, remove the disk to get to the EPB for easier cleaning. Inspect the brake shoes for wear and clean with a high-pressure water jet. Replace the disk before adjustment. There are two adjustment points. One is the Allen Key socket, and the other is the ratchet on the opposite side. Remove the plastic plug and rotate the disk in the forward direction until the hole is in line with the ratchet adjuster. Using a flat screwdriver through the hole, tighten the ratchet all the way. Then take a 32mm socket on a torque wrench and pre-set to about 60Nm. Turn the disk forward with the torque wrench while tightening the ratchet with one click at a time until the torque is reached and then release the ratchet by eight clicks back. Rotate the disk until the hole is in line with the Allen Key socket and undo this by half a turn. Tap the disk with a rubber mallet to release the tension. Tighten the Allen Key to 6Nm.
