Question
I have an S80 2000 Volvo and I would like to replace the brake pads by myself. I would like to know the step by step procedure on how to replace the brake pads, both the front and rear brake pads. Thank you Vedat in advance.

Answer
Hello,
You can find following the procedure for replacing of the pads...

FRONT BRAKE PADS...
Remove the securing spring and locating pins
Remove:
-the securing spring carefully so that it does not deform
-the protective caps  from the two locating pins -the locating pins, use hex socket 7 mm.


Remove the brake calliper and brake pads
Remove:
-the brake calliper from the holder
-the brake pads.
Hang brake calliper from a steel wire from the front spring so as not to damage brake hose.
Note! Do not depress the brake pedal while the brake pads are removed.


Clean and check brake calliper and dust cover
Clean and check brake pad mating surfaces in the brake calliper and calliper holder.
Check piston dust boot. Replace dust boot if it is damaged.
Note! If the dust boot is damaged dirt may have penetrated the cylinder. The brake calliper must be reconditioned.

Check the brake disc
Check brake disc friction surfaces.
If the brake disc displays signs of out-of-true, check its lateral run out. Replace the brake disc if it displays signs of heavy wear, variable thickness or similar.
Note! Minimum recommended disc thickness / replacement limit = 23.0 mm. Minimum recommended disc thickness when installing new brake pads = 23.8 mm.
