On 2014-’17 Range Rover models equipped with the High-Performance Brake Package with 380 mm front brake rotors, the customer may complain of squeal noises when the brakes are applied under light stops.

The cause of the noise is front brake pad resonance from the original brake pads. Land Rover has introduced an improved brake pad set (P/N LRO93886) to alleviate the problem. Land Rover recommends using a long-life lubricating grease for specific areas of the brake pad. Also, Land Rover recommends filing the top area of the new brake pad as indicated in Figures 1 and 2. There is only a 2º ± on the 45% chamfer. The brake lubricant should be applied to the edges of the brake pad as indicated in Figure 3.

Note: The bolts holding the caliper to the upright are torque to yield (TTY) and cannot be reused. The new bolts should be torqued to 133 Nm and turned 60º.

Brake Problems

Reducing brake drag on late-model vehicles is not accomplished by a single component; it takes a system.

Drivers and technicians rarely make the connection between fuel economy and brakes. Moving the pads back from the rotor by only 1mm can increase fuel economy by as much as three to five percent. For engineers, it is a huge gain that does not involve exotic materials or adding expensive components.

Why Brake Pads and Rotors Should be Replaced Together

Brake pads and rotors should always be replaced in pairs.  Pairing new pads with worn rotors could cause a lack of proper surface contact between the pads and rotors, resulting in noise, vibration, or less-than-peak stopping performance. While there are different schools of thought on this paired part replacement, at ADVICS, our technicians always recommend
