I see that the bulletin says "NOTE: Normal Warranty procedures apply". So this would typically be covered by warranty? My car is just with the dealer to get a new O2 sensor and diff under warranty so if this is a warranty matter I might tell them to fix this too.
I assume your car has the 380mm rear discs? (optional on the R-Dynamic). If so, and the rear brakes are found to squeal, I would think the Technical Bulletin applies. This should be covered under warranty as your car is still within the warranty period.
However a Special Service Message (SSM) has since been issued on 21/09/2018 with the title ‘SSM74090 - X152 (F Type) 19 inch Rear Brake squeak / squeal’ (attached).
Taken from the SSM.....
Issue: A customer may present an F-Type with 19 inch wheels exhibiting rear brake squeak / squeal. Although the noise does not indicate a degradation in functionality or braking performance, it may lead to customer dissatisfaction, and unscheduled retailer visits for repair action.
Cause: Under investigation by JLR engineering.
Action: Please pass on the following information to any concerned customers:
1. The noise may not necessarily result in a degradation of friction material performance.
2. Discuss with them the scenario’s when the noise occurs – see questionnaire below, and complete the relevant sections of it with the customer if possible.
3. Advise the customer that you will raise an EPQR so that JLR Engineering can review the concern.
Although your car has 20 inch wheels, some of the information may still be relevant?
Being as your car is already with the dealer for a new O2 sensor and diff, it would be a good idea to mention the brake squeal, Technical Bulletin and SSM to them.
