Do I need to de-pressurise the system to replace a front caliper?

The Haynes manual doesn't mention it but the Russek manual does

Cheers all

Incidentally, is it cheaper to buy Hydraflush from GSF with the postage or to go to Citroen?

Thanks again

Hi Jackyboy.

Wouldn't have thought so. If the caliper were permanently under pressure, the brakes would be permanently on.

Thanks for that Mike, makes sense really. I just wanted to chech because I want to do the job tomorrow

Hi Jackboy

The flushing agent is £50 for a 5ltr bottle from citroen, dont know what it is from gsf though.

As a safety measure, consider depressurising as a precaution against someone depressing the brake pedal when you have the caliper off and releasing accumulator sphere pressure. Unlikely to happen but....

Last time I bought hydraflush (5L) from GSF it was something like £16 plus postage.
Depressurising just takes a minute with a spanner; I'd do it before any work on the hyd system.
