Just had another service completed and have been advised the rear brakes are at 4mm. Does anyone know at what point the sensor will put the warning light on ? Or should I just bite the bullet and have these done now ? I only do 7K a year.
Funnily the front tyres are also worn ?

Thanks,
Steve

I believe (but stand to.be corrected) That the light comes on at 2mm. However, there are only 2 sensors to monitor 8 brake pads.

If in doubt, have them replaced, to avoid damaging the discs, and costing even more

Mikey, Thank you for your as always accurate response. I will probably replace the discs as well as they do seem a bit corroded as the vehicle does sit for long periods. Due back in June so will drop you a PM.
