Replacing TD5 Disco rear brake pads

Park the vehicle on level ground and put it in gear/park. When you jack one of the back wheels off the ground the handbrake will no longer be effective - even on the opposite side.

Slacken the wheel nuts (27mm) and then jack up one corner and place an axle stand under the axle. Remove the road wheel and the caliper can easily be seen.

The ABS wire is held to the brake hose by ywo yellow clips. Dteach the ABS wire, but not try to disconnect it or put any kind of strain on it.

There's always a small raised edge on the disc where the pad doesn't contact it right to the edge and this will prevent the caliper from sliding off. Carefully lever the pad/piston away from the disc as shown in this picture.

The caliper body is held to the support bracket by 2 x 12mm head metric fine thread bolts - both facing inboard and one at the top and bottom.

The caliper body will then lift away - respricted only by the length of the brake hose. The old pads will either stay in the frame or fall out.

The piston now has to be carefully pushed back into the caliper body. I use a 5-inch G-clamp to do this although careful leverage on the piston while the caliper is still on the vehicle will do the same thing (careful not to damage the disc though)

Slowly winding the G-clamp in pushes the piston all the way back into it's housing.

This picture of the old pads is a bit deceiving - there's actually only a couple of mm left on them. Manufacturers minimum wear limit is 3-4mm and the requirement for the MOT is 1.5mm minimum.

New pads are Mintex, which are a good make. They come with new bolts that are pre-coated with thread lock. It's ok to use the old bolts if necessary, but clean them and apply thread lock on them before re-fitting.

The caliper body replies on two pins that you should clean and re-grease at the same time. They just pop off and a quick wipe and coating of fresh LM grease will make sure the caliper works properly.

Clean the caliper frame and fit the new pads as shown.

The caliper pins have a flat-sided washer attached, make sure it's located on the body correctly.

Tighten the two bolts and then press the brake pedal a few times - it'll go right to the floor once or twice as the piston moves out to contact the new pads. The pedal will then go hard.

Re-attach the ABS wire in the two clips, replace the road wheel and lower the vehicle down, then the same for the opposite corner.

Always replace brake pads or shoes as an axle set - regardless of the reason for changing them. Braking efficiency must the same on the same axle - mixing pads or shoes is a dangerous combination.

New pads take a while to bed in on an old disc, so they will be below performance until they have been used a few times.

If you use cheapo pads - they are made to a certain spec and will no doubt work ok, but you may find they will start to squeak annoyingly long before they are due to be changed again.
