Renew BOTH sets of front brake pads at the same time – NEVER renew the pads on only one wheel, as uneven braking may result. Note that the dust created by wear of the pads may contain asbestos, which is a health hazard. Never blow it out with compressed air, and don’t inhale any of it. An approved filtering mask should be worn when working on the brakes. DO NOT use petroleum-based solvents to clean brake parts – use brake cleaner or methylated spirit only.
Apply the handbrake, then jack up the front of the vehicle and support it on axle stands. Remove both front roadwheels.
There are three possible types of pad retaining pin which may be used:
- Pads retained by large split-pins, and plate-type anti-rattle springs fitted.
- Pads secured in position with pins and R-clips, and wire-type anti-rattle springs used.
- Pad retaining pins are secured in position by a split-pin, with coil-type anti-rattle springs fitted over the pins.
Identify the type of retaining pin used, and proceed as follows.
On models with the first type of retaining pin, noting the correct fitted locations of the pad anti-rattle springs, straighten the ends of the pad retaining split-pins, and withdraw them from the caliper. Recover the springs from the top of the caliper, noting which way around they are fitted.
On models with the second type of retaining pin, remove the R-clips/split-pins (as applicable) from the inner end of each retaining pin. Noting the correct fitted positions of the anti-rattle springs, withdraw the retaining pins, and recover the spring from the top of each pad.
On models with the third type of retaining pin, using a pair of pliers, remove the R-clip/split-pin (as applicable) from the inner end of each pad retaining pin. Carefully withdraw the pad retaining pins, recovering the anti-rattle springs as they are released
On later models, remove the split-pins . . .
. . . then withdraw the pad retaining pins and recover the anti-rattle springs (arrowed)
On all models, withdraw the pads from caliper
. Note the location of any brake pad shims fitted.
Lift the brake pads out from the caliper
Brush the dirt and dust from the caliper, but take care not to inhale it. Carefully remove any rust from the edge of the brake disc.
First measure the thickness of each brake pad’s friction material (see illustration). If either pad is worn at any point to 3.0 mm thickness or less, all four pads must be renewed. Also, the pads should be renewed if any are fouled with oil or grease; there is no satisfactory way of degreasing friction material, once contaminated. If any of the brake pads are worn unevenly or fouled with oil or grease, trace and remedy the cause before reassembly. The pad retaining pins and anti-rattle springs should be also renewed if the pads are to be renewed. New brake pads, pins and springs are available from Land Rover dealers.
Measuring brake pad friction material thickness
If the brake pads are still serviceable, carefully clean them using a clean, fine wire brush or similar, paying particular attention to the sides and back of the metal backing. Clean out the grooves in the friction material, and pick out any large embedded particles of dirt or debris. Carefully clean the pad locations in the caliper body/mounting bracket.
Prior to fitting the pads, brush the dust and dirt from the caliper pistons, but do not inhale it, as it is a health hazard. Inspect the dust seal around the piston for damage, and the piston for evidence of fluid leaks, corrosion or damage. If attention to any of these components is necessary.
If new brake pads are to be fitted, the caliper pistons must be pushed back into the caliper, to make room for them. Either use a G-clamp or similar tool, or use suitable pieces of wood as levers. Provided that the master cylinder reservoir has not been overfilled with hydraulic fluid, there should be no spillage, but keep a careful watch on the fluid level while retracting the piston. If the fluid level rises above the MAX level line at any time, the surplus should be syphoned off, or ejected via a plastic tube connected to the bleed screw.
Do not syphon the fluid by mouth, as it is poisonous; use a syringe or an old poultry baster.
Apply a thin smear of high-temperature brake grease or anti-seize compound to the sides and back of each pad’s metal backing, and to those surfaces of the caliper body which bear on the pads. Do not allow the lubricant to foul the friction material.
Locate the pads in the caliper, ensuring that the friction material of each pad is against the brake disc. Note: The friction material on new pads may have a chamfered edge. The pads must be fitted with this chamfer on the leading edge, ie, this edge is the first part of the pad that the disc encounters in the normal direction of rotation
New pads may have a chamfered edge which must be fitted at the leading edge

On models with the first type of pad retaining pin, position the anti-rattle springs on top of the pads, ensuring that they are fitted the correct way around. Insert the new retaining pins into the caliper, making sure each pin is correctly engaged with its anti-rattle spring, and secure them in position by bending over their ends.
On models with the second type of retaining pin, locate the anti-rattle springs with the brake pads, making sure that the spring ends are on the inside of the pad. Slide the retaining pins into position, making sure they pass through the pad holes and over the spring ends, and secure them in position with the R-clips or new split-pins (as applicable).
On models with the third type of retaining pin, fit the anti-rattle springs between the pads, then insert the pad retaining pins. Make sure each pin passes through its anti-rattle spring and both pads. Secure each retaining pin in position with an R-clip or new split-pin (as applicable).
On all models, depress the brake pedal repeatedly, until the pads are pressed into firm contact with the brake disc and normal (non-assisted) pedal pressure is restored.
Repeat the above procedure on the remaining front brake caliper.
Refit the roadwheels, then lower the vehicle to the ground and tighten the roadwheel nuts to the specified torque setting.
