I bought it accident damaged from a couple who had crashed it into there gate post. I did the repairs as they were only superficial but at the mot it failed brakes and pipes, in a way I'm glad it did as otherwise it could have been worse!

The couple I bought it off had no real idea about cars so it wouldn't suprise me if they had put the wrong fluid in it.

As for the easi bleed it just left dent lol

[Shackeng]

Just to not the fluid that has come out of the pipes has been discoloured but normal viscosity, but the fluid in the reservoir is like treacle.  .....

How long have you had the car? I sounds like the reservoir has been topped up with something other than brake fluid

Just my thought. I suspect it may have been topped up with power steering fluid. It may be easier to remove the reservoir, not difficult, and clean it out, refit with new seals, or even another uncontaminated reservoir.  In any event the whole system needs a proper flushing. Also if it is contaminated fluid, you would be well advised to replace all the caliper seals as well.

Well like I said, what's coming out of the calipers is not bad and I wouldn't say contaminated so I think I will be ok there. My worry is getting it through the pump. I'm guessing this is why the easi bleed struggled and couldnt manage on it's own!

Have I missed something here? if there is a pump its new to me!

[star_whites]

It oes through the abs pump if I'm correct??

I don't. You have found something "like treacle" in the reservoir. That can't be brake fluid, so the whole system is now potentially contaminated. The seals in the system may well not be compatible with whatever has contaminated it and could fail.

At the minimum the master and slave cylinders should be rebuilt with new seals and the brake lines flushed through with fresh fluid or meths, IMHO. The braking system is too important to take any chances.

OOOOps, shows what I know!, but I double Kevin's comment on contamination, the whole system is now seriously suspect.

Having seen an aircraft removed from service for 17 months whilst EVERY o-ring and seal, in every join and component, was replaced because an idiot (and no, it wasn't me) put 1/2 a litre of the "wrong" hydraulic fluid in a system that contained 27 litres. The error was found after the system had been run for 30 minutes, so it was not possible to limit the contamination.

The difference in fluid could have caused seals to swell, weaken and possibly soften... therefore the whole system had to be sorted.

If you wish to take a risk with your brakes ....  it is your choice .. but the day you NEED the brakes and that contaminated, softened seal decides to give up and you lose all brake pressure ......

EDIT .. and before Shackeng asks .... OX87 in an OM15 system

I'm not so sure that it does in normal road use  ie when the ABS pump hasn't been operated. Otherwise you wouldn't need the pump cycled to bleed the brakes 'properly' after the system has been opened up to replace major pipes or if you have managed to get air in the system.

  That ended up as a VERY expensive 1/2 of hydraulic fluid

yup .. but that 1/2 litre of synthetic oil in a mineral oil based system ........

I am sure that will not be the last time, I've certainly come across a similar instance, but fortunately it was only a slightly different grade of oil in a Griffon engine gearbox, and I believe was cured by a drain, flush and refill.

yep, in normal use the fluid will go in through one of the valves and out again. The pump recirculates the fluid in order to re-apply braking after the ABS has operated. For this reason you might have got away without contaminating the ABS valve body too badly. I'm not sure what type of seals and rubbers are used internally but because there is a set for each wheel I might be inclined to suck it and see. Then again, I can't see a 2nd hand ABS block being that expensive, for peace of mind...

[star_whites]

The biggest problem I can see is risking getting air in the abs pump by removing any of the brake components prior to the pump. Obviously I don't have a tech 2 reader so it would be a case of suck it and see.

On another note my car spares replaced the eazibleed no questions asked!
