Hi Col hf

I am sure Paul H will be along soon, he knows his way around the C4 and will no doubt be able to help/

The brakes on your car should be the same as the front ones on the 2010 on C4 and there is a write up I did here http://www.citroen-owners-club.co.uk/citroen/topic/21408-new-c4-front-brake-pad-clean-or-replacement/

 

Also the following is from the Citroen service box workshop procedures for your car with some comments:

 

2. Removing

Untighten the wheel screws.

Lift and support the vehicle with front wheels suspended.

Remove the front wheels.

Remove the spring (1) which holds the caliper against the bracket (use a screwdriver to lever out the ends where they go in the holes).

 

Remove :

• The blanks covering the ends of the plastic parts containing the caliper guide bolts (2).
  
• The bolts (2) - a hex bit may be needed for this, could be 7mm.
  

CAUTION : Take care not to twist the brake hose .

N.B. : The brake caliper must not remain suspended by the brake hose.

Move aside the brake caliper (3) and secure it to the bodywork - you could hang it up using a welding rod or something similar.

Push the pistons back ; Using tool [1] (insert a shim between tool [1] and the pad to push the pistons fully back in their housings). This tool is like a big set of pliers but I would think a large g clamp or similar will do.

Check the brake fluid level.

Remove the brake pads .

3. Cleaning

CAUTION : Do not use compressed air to clean the brakes.

3.1. 1st possibility

Clean the brake disc and the brake caliper, using an approved brake cleaning product.

Allow to dry and to drain.

Wipe with a paper towel.

3.2. 2nd possibility

Use an approved dedusting instrument (refer to the Material and Equipment Catalogue).

4. Refitting

Visually check :

• The seal around the piston
  
• That the protective gaiters are in good condition and correctly adjusted
  
• Wear of the brake discs  - the new thickness may be 26 mm and the minimum 24 mm but if the pads are worn enough to need replacing than chances are the discs will be worn to the minimum and need replacing.
  

Replace any defective parts.

CAUTION : No trace of grease, oil or lubricant can be tolerated on the brake pads.

Refit :

• The new brake pads
  
• The brake caliper (3)
  

N.B. : At each removal, systematically replace the screws (2).

Refit :

• The screws pre-coated (2) (New bolts) ; Tighten to 27 Nm (but it is better to fit the bolts after the springs)
  
• The blanks ( as "a")
  
• The spring (1) - these springs may be difficult to fit back, make sure the pistons are fully pushed in- fit one end of the spring to the caliper, wearing gloves hold the other end of the spring in its hole with a thumb and then with difficulty, use the other hand to fit it over the carrier. Check the spring is pushed fully in place. Trying to fit the spring without first pushing the piston back and with the caliper bolts in place does not work.
  

Check the brake fluid level and top up if necessary.

Refit :

• The front wheels
  
• The wheel bolts
  

Return the vehicle to its wheels and tighten the wheel bolts (100 Nm).

ESSENTIAL : Apply the brakes, with the engine running, several times before driving the vehicle.

If you have replaced brake pads before these are not much different to most cars.
