Citroen C3

[vtr]

Hi I am brian I have a 54 plate citroen c3 and I want to change my front brake discs can anyone give me any tips on doing this? I have the tools to do it including a torque wrench which I haven't used before so can anyone tell me the torque settings for my car?

It would probally be more beneficial for you to get a haynes manual as it covers every aspect of your car.

 

1 remove the wheel

2 remove the 2 torx grub screws securing the disc to the hub (next to wheel nut holes)

3 remove caliper

4 remove caliper carrier 2x bolts

4 pull disc off. if stuck hit with a big hammer to shock it.

5 apply loads of copperslip on the flange that the disc sits on and reverse above procedure

Do you know what i need the torque settings to be set at for putting the nuts back on?

Brake disc screws 10 Nm

Caliper guide pin bolts 30 Nm

Caliper mounting bracket bolts 105 Nm (a torx bit may be needed)

Wheel bolts 90 Nm.

 

If the new discs are grease covered for rust protection this must be removed before fitting using brake cleaner. If they are from Citroen and are silver painted this can be left on after wiping with brake cleaner since the brake pads remove it from the friction area and the paint then protects the rest of the disc against rusting.

 

Fully clean (a file helps) the hub and back of the disc where they contact to make sure there is nothing that will prevent the disc seating flat against the hub. After fitting the new disc on, fit the wheel bolts (with spacers such as large nuts or washers) to hold it in place and then check the disc run out using a dial gauge - the max from the Haynes manual is 0.05 mm - if above this turn the disc on the hub and check again, if still too high remove the disc and check the contact areas are clean/not damaged/marked.

 

The friction material on the new brake pads if from Citroen will be chamfered and the chamfer should be at the top when the pads are fitted. The caliper pistons do not need rotating when pushing in to accept the new thicker pads. http://www.citroen-owners-club.co.uk/citroen/topic/20395-brake-pads-fitting-direction/
