orangespanner stocks a large selection of brake fluid for your Citroen C-Zero. Most modern cars use DOT 4 in their braking system and on some vehicles the same fluid is used in the operation of the clutch. Over time brake fluid will absorb moisture resulting in a 'spongy' brake pedal so it is very important to follow your vechicle's service scehdule and regulary change the brake fluid. In some cases you can upgrade your DOT 3 to DOT 4 or even DOT 5 (non ABS models only) or DOT 5.1. We stock brake fluid in 500ml, 1 Litre and 5 Litre containers.
