 In a previous post (below) the suggested brake calliper bleeding order is the opposite of what is "NORMAL": IE bleed the brake calliper the farthest away from the master cylinder FIRST.

WHY is the brake calliper bleeding sequence different for the C6 ? (using external air pressure to power a Pressure Bleeder)?

Is the brake bleeding sequence below for RHD C6 ?

In any case, Why are front callipers bled first ?

"Connect pressure bleeding kit with suggested maximum pressure of 1.5 bar not 2 bar as in the instructions (some white stress marks showed in reservoir plastic so didn't want to push it the official Citroën pressure). Bleed callipers in correct order (FL >> FR >> RL >> RR)."

 The Technical Document available - Click Here - does say bleed (FL >> FR >> RL >> RR) in sequence.

Why do you think that's not correct when Citroën engineers created the document?

Other UK/European build cars I have owned (from back in the 1980s) use the same sequence and is considered the "NORMAL" way to bleed brakes, purging any old oil/air from the system closest to the master cylinder as the front brakes do most of the car braking.

 Thanks C6 Dave .... I asked in another post if this brake bleeding sequence in the Citroen document is for UK / RHD C6s ?
Brake master cylinder in UK C6s is closest to FR caliper
