Mityvac MV8020 Vacuum Pump Kit with Pump Bottle (Bleeder KIT)

I had a problem with it not holding pressure. Got a refund and now leaving a good review because it was easy to return.

The quality of this tool is just brilliant. I've used it to bleed the brakes on a few cars now and it has always performed without fault. Would I buy this again. Definitely

Read several reviews several of which were poor but decided to try it anyway. Didn't even work one time. I bought this mainly to use in my motorcycle. System wouldn't hold a vacuum at all and the pump handle is only held in by a pin that Kept falling out thus allowing the handle to fall off. After about 45 minutes to an hour of attempting to get this to work I got frustrated and went to an auto parts store and bought a one man bleeding bottoms for $9.94. It worked so well I was able to bleed the brakes on my motorcycle in 10 minutes. I wouldn't suggest this product to anyone

The unit is ok but could be improved. The fit of the plastic tubing is not perfect, sometimes when the pipes aren't straight it will suck air in through the hose, particularly the short hose between the pump and the container/reservour. This could be fixed with better hoses and/or by moulding a ridge on the plastic to give it a tighter fit. The little rubber angled attachments that go on the brake nipples also struggle with the smallest size nipples and are sometimes prone to drawing in air if they aren't perfectly straight (my car has small caliper nipples on the fronts, big on the rear).If you use it very carefully it will work ok, I used it to do an initial bleed then finished with the old-school two-person press pedal, open, close, lift-off method to get a rock solid pedal feel.It would be very handy for doing a full fluid change since it can draw through large quantities of fluid very quickly.In all I'm giving it 3 out of 5 stars.

Excellent
