Brake Problems - Master Cylinder
« on: 04 December 2011, 13:22:52 »

Ok, I've just got round to removing the brake master cylinder off my 2001 2.6 and I have an urgent question::

The master cylinder I have removed has the numbers 2017 (symbol) 1 written underneath, however the one I bought off albs had 2017 (symbol) 2 written on it. Does this mean it's the wrong one or is it just a newer model????

Yep, some master cylinders on the Omega had a 25/20 split bore feeding front/rear. If the one from Albs has identical markings to yours should all be OK

Well hopefully the last update on my brakes, I've replaced the master cylinder and completely bleed the entire system and I have brakes  :D

There not fantastic due to new pads all round and rusty discs due to how long she's been stood but I think after bedding in the new pads and cleaning the discs up they will be ok, believe me they are way better than they were!

Just headlight to dismantle and check if bulbs are seated properly ( due to high beam on drivers side) and she will be off for another mot!! :) :y

Thanks for all your help, especially Albs, top man  :y

Next decision is whether to stick with dot 4 or flush it again with the expensive race fluid I've been given. The guy says it's ideal for my mig especially due to the size of her. He recons it will improve braking distance!

Going from vague memory rather than knowledge - racing fluid ,fully synthetic ? not compatible with other types of fluid ?
If this is the case you would need to get all of the old fluid out of the system before putting it in.
Personally,I think Dot4 is more than up to the job.It would take some pretty extreme driving on the road to boil it imo.
