Hi Mike and All
Time is approaching to start the Annual Service.
This year I need to replace the Brake fluid
Can anybody advise me if, during the process of bleeding/flushing out the system:-
a) Does the brake fluid pass through the Master Cylinder, ABS system and then Calipers and out via the bleed nipple?
b) Or is the ABS by-passed during the normal bleeding process?
c) If the the normal bleeding method does by-pass the closed ABS system, as I suspect, how on earth does one change that fluid?
I await in anticipation!

Re: Bleeding S type Brakes
Hi Oldtimer,
I replaced my brake and clutch fluid a few montha ago, the pipes seem to indicate that it passes from the master cylinder, through the ABS valve block and on to the calipers.
To save using too much fluid I used a large syring and emptied the reservior, refilled with clean fluid, then whilst my wife pumped the pedal I bleed it off at the calipers until it all showed clean fluid.
If my MOT guy fails the steel brake pipes then it cunifer and a real sod of bleeding from scratch, anyone know if these vacuum bleeders are any good?

Hi Brian,
Don't know about the vacuum type of bleeding kit. For years, well for ever, I've used a piece of rubber tube and a jam jar, and a helper on the peddle.
I recently purchased an Ezzy Bleed kit from Halfords. Whilst I was agonising wheather it would be any good another customer sidled up to me and said "pssst you wonna buy dirty picture" No he did'nt. He said "Realy good bit of kit. So I bought it.
It comprises of reservoir that attaches to the exsisting reservoir by way of a choice of adaptors.
Fill with brake fluid and pressurise using a hose provided between the supplementry reservoir and the tyre. Then go to each wheel and bleed away.
It sounds fine, it looks fine, lets see if it does what it says on the tin!
When I've used it I'll report back
Oldtimer
PS Aint doing it until it warms up a bit cos I'm old

Hi Oldtimer,
I've got one and they are very good, I leave the bleeder reservoir empty so there is less chance of spillage onto the paint and a tyre reduced to 20 psi, but for some reason that I can't remember I didn't use it on the S type, probably forgot I had it! it has done most other of our cars.

Re: Bleeding S type Brakes
Hi Brian,
Interested to hear that you have an Ezzy Bleed kit and that it works well.
BUT
When the bleeding process is complete and perhaps some fluid is left in the secondary reservoir is it necessary to bleed out extra fluid in order to empty the secondary reservoir and a little out of the vehicle reservoir in order to prevent spillage? OK OK Yes de-pressurise the Bleed kit first.
Brake fluid really is horrible stuff , I don't even like getting it on my hands, let alone anywhere else!

Re: Bleeding S type Brakes
sorry Oldtimer I didn't make it clear,
I never but brake fluid in the ezzy bleed reservoir, just use it as an air reservoir. I may have to release the air connection to the tyre a few times so as to top up the cars reservoir and then re-attach the easy bleed system, but at least I won't spill any on the paintwork. besides I usually get through most of the ltr bottle of fluid just to make sure the old stuff has gone, so the small ezzy bleed reservoir wouldn't be big enough anyway.
Just a small tip, put a proper release oil in the bleed nipples the night before or earlier so that they will come loose easier rather than break. I use a 3M product.
Best of luck

Re: Bleeding S type Brakes
Hi Brian and All.
Back in January I was asking about Ezzy Bleed Kit.
An update as promised. So I recently used my newly acquired Ezzy Bleed Kit and followed the instructions. I filled the bottle, with about 750ml and it worked a treat.
How ever I have two observations
First. I need to make a simple stand to stop the bottle falling over. Maybe a bit of 4x4x2 lump of wood with about a 3inch hole to stand the bottle in
And - When disconnecting off the car reservoir, absolutely no spillage but the car reservoir was filled to the very brim. I acquired a very small syringe from the chemist (50p) used to administer child medicine this allowed the brake fluid level to reduced to the correct level.
Conclusion- Very good , Recommended
