Front disc brake and pad change

[B3NNETT]

Firstly jack and chock the car properly using axle stands.

Remove the front wheels from the car.

Undo the 2 13mm bolts holding the caliper to the pad carrier.


At this point before i remove the caliper completely, I like to prise the piston back into the caliper. doing it now saves finding something to force it in, or worrying about ruining the back of new pads trying to squeeze the caliper back over them.

Hook the caliper up out of the way making sure not to put any stress on the brake lines. (I use a old welding rod bent into a s shape and hooked over the spring)

Now remove the pads from the pad carrier, and undo the 2 19mm bolts holding the pad caliper to the car.



Next remove the 2 torx screws holding the disc to the hub. (top tip, give each torx screw a tap with a hammer to 'shock' of any rust or crap build up. helps prevent rounding.)



Now remove the old disc.

Now in reverse of how it came of, refit the new disc and the 2 torx bolts.

Refit the pad carrier with the 2 19mm bolts.

Refit the new pads, making sure to add a little bit of cooper grease to the back face of the pads and the part where they slot in the carrier, to avoid any excess squealing.



Slot the caliper back over the pads and bolt on with the 13mm bolts.

Wala nice new brakes



Important: remove the hook over the suspension that was holding the caliper.

Refit the wheel, and repeat for the otherside.

Remove the car from the chocks.

Make sure to pump the brakes to get the pressure back before driving the car.


Apologys for the poor quality photo's, they will be changed the next time i do another set of brakes.

Now as fine a write up as that is, a couple of points worth mentioning,
Removing brake fluid filler cap before trying to ease the pistons back in the calipers, also worth wrapping a cloth around the master cylinder in case any fluid overflows.

If you do not have a brake rewind tool and your pistons are very stiff you can use the wooden handle from a hammer or the like, if you are changing the pads anyway then get a large screwdriver or lever and ease the piston back with the pads..both these methods save your pistons from damage
