Brake bleed sequence.

Hi all,

Sorry if this has been covered already but if so I must have missed it and therefore my request.

When bleeding the brakes I always was having the idea (since about 40 years) it should start with the wheel the fartest away from the main brake cylinder and to work towards the closest. Thus in my opinion the sequence should be, on a LH driven car with the main brakecylinder on the left (and the ABS unit on the RH side): RHrear, LHrear, RHfront and LHfront, however when reading the rave it shows exactly the opposite, namely: LHfront, RHfront, LHrear and RHrear, this to avoid possible damage at the ABS unit ? Can someone shed some light on this please ???

Sorry but this might look for some of you as a double posting

i always start at the nearest and end up at the furthest, does this mean i have to find my college notes after thirty five years of putting them in a safe place in case i need them one day.

Reading this shows to me not only the driving direction is opposite on the continent compared to the uk but also the way of bleeding brakes ......

Anyway, have read on another place that someone mentioned that the FL should start with the nearest and work up to the farthest, it was even documented as been "special" ??

It always used to be the case on traditional systems you bled the furthest 1st. When diagonal split braking systems came in it was less critical except you did the two on one circuit then the other.

Theoretically with ABS the distance would be measured from the ABS pump not the master cylinder. Also with ABS I was taught you should use a pressurised resevoir rather than pedal movement. However the Rave disk does detail the pedal purge method and list the sequence LH-F, RH-F, LH-R, RH-R

Thats spot on in my opinion With older vehicles? yeah I always started from the furthest bleeding nipple. Bought one of them self-bleeding/pressurised resevoir kits last year from Machinemart(less than a tenner)! 10-15 mins to suss how it worked! brilliant bit of kit, didn't have to touch the brake pedal

so we are all right, and we are all wrong then, but its the vehicle that chooses
