The Brake Escape

I had new discs and pads all round on the XFR a month after purchase, at no charge courtesy of Jaguar. So when the brake pad wear warning came onto the screen earlier this week after 9000 miles from the new set, I was a bit shocked. Yes, I'd be warned that the traction control could destroy a set of rear pads in under 10k miles, but most of my time is spent on A roads and motorways, not B roads and hill climbs. Still, off to the dealer it went this morning.

I just got a call. The pads and discs are fine. The sensor is faulty and needs to be replaced.

Good news but I presume it isn't one of those £12 things that slot into a clip on the pad?

Yes sensors are killers for telling lies. My car has been telling me I need a brake service in 3000 miles and has done so for the last 2000 miles......

That's nothing to do with the sensor.

The brakes are different to an oil change or service, which is more condition (and time) based.  A pessimistic estimated life is calculated when the car is new or brakes replaced and it counts down from that point.  The rears dropped down to 3,000 miles after about 30,000 on mine and stayed there for months.  They were checked at the service and were only 20% worn so they adjusted the compute accordingly, so it should now be pretty accurate.

If not, there's a sensor which tells you when they are low, so that's all you should go off.

I just assumed they get shagged out with that traffic creep thing.

Must make a change from the normal getting-shagged-out-from-braking from-270kph thing that normally happens.

No, mine should get to 60k+ miles pretty easily.  Do you know if yours are the originals?

Well the sensor was £30, so with labour and VAT, the bill was £101. Service and MOT due before Christmas, but that's all covered by the service plan.

I've managed about 50k so far from the rears on the M5 despite the TC light seeing a lot of action.

Is that not covered by the 2 year warranty you get when you buy a used Jag from a Jag dealer?

My rear brakes were new at the time I bought the car; it's the front ones that the computer tells me about.
Martin

My fronts are going to get to 80,000 of the updated computer calculation is right.  So you've anywhere between 3,000 and 20,000 miles to go.  Maybe.

I wondered that too. But was told not. It seems that pretty much anything to do with brakes is treated as a consumable item. I think I might ring the service manager on Monday and ask him for more details and follow it up direct with the warranty people.

The computer in the 535d said the rears had 30,000 miles to go when I looked last week, but the warning light came on yesterday, 600 miles to go.  A bit of a pain as it's an extra visit to the garage,but can't complain too much as it will have done 50,000 miles.

That's quite some mileage in a week.  
Martin

It certainly is.
