brakes

had '01 S80 in shop the otherday to check front window operation. they were both sticking. need tires, so also had brake inspection done. brakes are VERY near done. The rotors do have a "lip" so to speak on outside edge, from being worn. one of the techs,(formerly worked in a shop that did some Volvo work), mentioned that Volvo does not recommend truing, resurface, etc., the rotors. they require(?) replacing rotors?? Any ideas? specs for resurfacing? Car only has 125,000 miles. hard to imagine that rotors need replacing. car is not driven aggressively.

With 125 K on the car you have done very well with the brakes. Rotors and pads an easy DIY project

Volvo do not recommend skimming.

On the front brakes the minimum disc thickness/replacement limit is 23mm or 23.8mm if fitting new pads. On 16" discs the figures go to 25mm and 25.8mm.

On the rear brakes the minimum disc thickness/replacement limit is 10mm or 10.7mm if fitting new pads.

If skimming would take them near to or below those figures it is a non-starter.

Many cars out there have rotors that wear. Softer rotors with specific compound pads give you the ability to have decent braking with no power booster assist if engine dies. The vehicles with the other compounds and harder rotors have greatly increased stopping distances and that is if the person behind the wheel has very strong legs. Hard rotor vehicles are not sold in countries where there is a standard for dead booster stopping distance with specified pedal force.
I have a 2003 Ford Expedition and its brake rotors on front lasted one set of pads. The rears seem like they may be good for a second sets of pads.

thanks for the advice fellas! I think I will just bite the bullet & get pads & rotors.
