Vac bleeder

Ron1000 · 27-10-2022, 04:24 PM

Any recommendations on a vac bleeder. My 899 callipers have arrived, i might as well bleed them up properly.

Thanks again guy’s.

Do you have a compressor or are you looking for a manual pump?

Ron1000 · 27-10-2022, 05:22 PM

Manual pump style.

I use one of these:

One of the best pieces of kit I've splashed out on.

But, be aware that if you are using this type of kit you very often need to put a couple of wraps of plumbers tape around the threads of the bleed nipple to maintain a seal around the loosened thread.

Otherwise the suction drags air in down the sides of the loosened thread and it appears as bubbles in the clear pipe making you think you are still drawing air from the Caliper.

I’ve got one like this that came from hein-gericke that’s served me well for 20 odd years

I can recommend the MityVac as per this thread:

I worried that My Mityvac was going to struggle with bigger jobs but it hasn't.

It handled changing the Brake fluid in My Discovery really well, despite the system being huge with ABS etc, all I had to do was a couple of additional pumps on the handle to top up the vacuum part way through.
I've also used it a couple of times to prime the 2T Oil hoses from the remote reservoir to my outboard.

The kit has many other test and maintenance uses in both Vacuum and pressure modes that I used in my 'Man-Maths' justification for spending what is a reasonable sum of money on a good piece of kit rather than an adequate one.
But as you can imagine I've only actually used it as above.

I do however have a big compressor powered Vacuum pump for changing the Oil in our cars.

^^^ my experience with the Sealey vacuum pump is that it drained my compressor tank very quickly, the hand operated vacuum pump works well with the proviso that thread tape is needed on the bleed nipples or you can be there all day drawing air through the bleed nipple threads.
