Questions and comments on replacing your volvos discs and pads.
Brake pads convert the kinetic energy of the car to thermal energy by friction. Two brake pads are contained in the brake caliper with their friction surfaces facing the rotor. When the brakes are hydraulically applied, the caliper clamps or squeezes the two pads together into the spinning rotor to slow/stop the vehicle. When a brake pad is heated by contact with a rotor, it transfers small amounts of friction material to the disc, turning it dull gray. The brake pad and disc (both now with friction material), then “stick” to each other, providing the friction that stops the vehicle.

about a month ago i had my rear brake pads replaced for 350.00, i dont want to pay that much for my front pads(which needs replacing now). i dont usually work on cars but think the time is now. any suggestions on how to making my first brake job as seamless as possible. thx
MVS Forum Member precopster replied:
$350 just for pads or were rotors replaced as well??
A pair of front rotors can be purchased for as little as under $110 and rear rotors for $80 but GENUINE VOLVO rear pads alone are $31 alone from FCP Groton:
Check your rotors for deep grooves and for overall thickness; they should be no less than around 24mm thick, but if somebody will chime in with minimum disc thickness on your car that would be great.

Fortunately brake work is fairly straightforward, and as you have found, can really save you a bundle if you DIY. Do you have a friend who might be able to assist you for your first job? If not, I’m sure we can help you through it. It’s basically just jacking up the car, removing the wheel, removing the caliper, changing the rotor, changing the pads and putting it back together. All simple nuts and bolts stuff.
