Changing the brakes on a Mazda 6 is a relatively easy procedure for those with a moderate knowledge of auto repair. The new parts cost only about £39, but paying for professional labour can easily bring the total to upward of £130. Luckily, the procedure for replacing brakes on a Mazda 6 is simple and virtually the same for older and newer models. You will need a few tools but nothing too specialised.
Loosen the nuts on the front wheel.
Jack up the front of the vehicle.
Remove the wheel.
Use a 3/8 ratchet to remove the caliper slide bolts.
Remove the two caliper brake mounting bolts and then the entire assembly.
Put the assembly on a suspension control arm.
Remove the old brake pads.
Retract the caliper piston by using a large adjustable C-clamp and carefully inserting a flat wrench between the clamp and piston. Then screw the clamp until the piston is retracted flush with the caliper.
Remove the rotor by first unscrewing the two flathead screws that hold the rotor to the spindle.
Remove the tight rotor on the spindle by inserting a 6mm metric bolt in the 6mm hole.
Degrease the new rotor and install. Tighten the screws.
Carefully install both the caliper and new pads. Tighten the bolts. Replace the wheel and nuts. Lower the wheel and tighten lug nuts.
Replace the wheel and lower the vehicle. Then tighten the lug nuts.
Remove the rear brakes by repeating the previous steps on the rear wheels, stopping at removing the rotor.
Keep the spindle from turning when removing the rear rotor by putting a breaker bar between the lug studs while loosening the flathead screws.
Retract the piston with long-nosed pliers and turn the piston clockwise until it is flush with the caliper.
Reverse the steps to install the new brakes.
Clips that the brake pads sit in often break, so check that they're all there while you're changing the brakes.
