2006-2009 Range Rover Sport
I read about some of you 2010 owners complaining about brake squeal. I captured this Special Service Message for MY10 front brakes squeal today (applies to non-Supercharged engines only, including LR4s):
As a reminder, Special Service Messages are not TSBs, so don't go to your dealer demanding the fix based on the above report as you may just piss them off. A SSM is an acknowledgment from Land Rover to dealers that its engineeers are aware of a possible problem with the car and are working on a permanent solution. In this case they think they may found it but they need more verification and feedback from dealers before issuing an official Technical Service Bulletin. Therefore, the fixes suggested within the SSM may or may not be final, the message may be withdrawn or modified tomorrow, and until an actual TSB is issued the dealer is not obligated to comply as the parts they need may not even be available yet.SSM# 43817

The design of the outer brake pad has been changed to eliminate a 5 khz frequency forward squeal which may be found on some vehicles. The pad can be identified by a small mass found on the outer pad only. See photo attached.
Upon customer complaint only, replacement of the brake pads will be required. Order LR021253 Kit - Caliper Brake Pad.
Please record any brake squeal noises where possible and attach to an EPQR. This is the only way to identify what frequency noise is being produced and for Land Rover to develop counter-measures.
