Brake lining warning on dashboard

[Mark.merc]

Message on dash says Brake lining wear visit workshop.
Does that mean I need new front disk pads or rear or all four?
Any help in what sort to buy would be much appreciated.

A quick look through the wheel spokes should determine whether the fronts , rears or both are needing replacement.
You are aware you have SBC braking and need to be very careful replacing the pads? You could lose your fingers if you aren't aware of the dangers. Best left to a MB indie IMO.

Your local dealer is probably your best bet for new pads. You can be sure you are getting the correct ones using your Vin# to match them. They are very competitive compared to ECP and other motor factors.
