Shared brake and clutch fluid reservoir.

Had this happen on another car,I used a large syringe with a small diameter plastic hose on the end of it to suck the old fluid out,
Not sure if this is possible on the Mondial reservoir..

 

Can you simply bleed it out of the slave until its just empty in the resivior, fluid would still be in the feed pipe to the master cylinder, then refill it with fresh fluid and continue bleeding until you have clean fluid at the slave bleeder.

 

+1, and don't spill a drop on the paint!

 

buy one of these and suck the fluid out of the reservoir. Also brilliant for one-man bleeding. Extremely well made, I can't believe how cheap it is.

Thanks for the link Ian.

As for sucking it out is the way to go, pumping it through just pushes the rubbish built up in the reservoir through the master and slave and it gets stuck in the check valves in the master cylinder.

 

How's it work?

 

a handheld vacuum pump that generates a lot of vacuum but with plenty of control - you can empty a fluid reservoir without getting the level too low and introducing air. Refill the reservoir with new fluid, attach the pump to bleed nipple on each caliper and pull the new fluid through. Quick and easy.

I used to use an oil/brake fluid extractor hooked up to a compressor but they're all or nothing in terms of suction. Easy to spill fluid to.

I did the 575's brakes recently with the handheld, about 20 minutes for a complete fluid change and the pedal's never been firmer. Cars that aren't used much should have fluid changed annually. I do the Indy car every race meeting.

Top tip - refill the reservoir with a different coloured brake fluid, then you can see when the new fluid comes through at the caliper.

 

Thanks....I've used the compressor driven one too, but they're not great. I'll get one of these.

 

another great idea someone put me on to, is buying surgical tube from a pharmacy, rather than the cheap nylon hose we've always used. The soft surgical hose goes on the nipple easier and the seal is airtight.

Also, before you start, take the bleed nipple out completely and wrap a couple of turns of thread tape on it, then refit but not tight. The tape will stop air getting past when you crack the nipple to bleed, also eliminate any leaks when you tighten it.

If you have aluminium calipers, this is a must-do to prevent electrolytic corrosion between the caliper and nipple.

 

I have one of those,well a similar looking tool,
Worth it's weight in gold as my wife got sick of helping me pump the brake pedal..

Very good tip using different coloured brake fluid.
