Mityvac MV8510 Silverline Elite Automotive Brake/Clutch Bleeding, Diesel Fuel Priming and Vacuum/Pressure Testing Hand Pump, Ergonomic Design, Zinc-aluminum Die Cast, Dual Converter, 2" Compound Gauge

My 2nd purchase. They usually last me 3 years. Great product! Highly recommended.

This review is about how I used the MityVac in combination with the Motive Power Bleeder to do a brake fluid job and be able to handle a contingency needing vacuum pressure. This thng works. Made bleeding brakes and replacing brake fluid easy for one person to do. I did not use the Motive Power Bleeder pump container to store the brake fluid. Instead I used the brake fluid reservoir as the fluid supply, and this kept the Power Bleeder bottle clean. When doing it this way you must be carefui to fill the brake fluid reservoir before doing each wheel so as not to accidently empty the master cylinder and introduce air into it, like I did when doing the last wheel which is closest to the master cylnder (oops). When doing the closest wheel you need to keep a closer eye on the fluid level in the reservoir because it empties faster than when doing the other lines (rear passenger side flows slowest since it's the longest line and the front driver side flows the fastest due to being the shortest line). If needed, a tip for a better seal on the master cylinder brake reservoir cap is to put a light coat of silicone grease on the rubber washer (silicone is compatible with rubber whereas petroleum based lubes are not).I fixed the problem of accidently emptying the master cylinder and was able to (I prepared ahead of time for this just in case) bleed the master cylnder of all air without having to disconnect any brake lines:1. Tool used - Mityvac MV8510 Silverline Elite Hand Pump2. Rubber stopper for the brake fluid reservoir was a solid 1-1/8 inch rubber sink stopper (size the 2010 Dodge Dakota takes and is equivalent to a #6 or #6.5 lab stopper). Drilled a small hole in it for a barb hose connector. You'll need to get a stopper that fits your vehicle.3. Connect the hose from the barb of the MityVac to the barb of the stopper.4. Put a light coat of silicone grease around the edge of the stopper and place the stopper into the opening of the master cylinder brake reservoir opening. May have to use hand pressure to hold down the stopper until a vacuum is established, depending on how hard/soft the stopper is.5. Using the MityVaC pump a vacuum of 15 to 20 psi, repeatedly until all the air is sucked out. You'll know when all the air is sucked out when the gage holds a vacuum without dropping. The gage may drop slowly if the seals are not tight at the barbs, and if you have leaky connections you can use a gasket type sealant to make them airtight. When air bubbles in the master cylinder are extracted by the vacuum pressure, the gage will 'pop' to a less negative pressure, requiring another hand-pumping.6. All air is out. Test brakes. Firm braking again - done.So, with the combination of the Motive Power Bleeder and Mityvac MV8510 Silverline Elite Hand Pump (in case), you can do a brake fluid job easy and neat, all the while keeping the equipment clean.

When I was making a decision to buy this pump some people were stating a nice case with attachments in their review and others stated just receiving the vacuum pump. It would have been nice to receive a cup for bleeding brakes. I ordered this because wanted a metal vacuum pump. I have an attached a picture with this review for others to know what to expect when purchasing. I haven’t used it yet but the unit seems well built. If it pulls vacuum and holds then I’ll be keeping the unit. I’ll provided a follow up of how it performs.

The MV8510 tool is diecast metal and it will outlast the less expensive plastic ones. It is a high quality tool which includes a vacuum/pressure gauge and it pulls a vacuum quickly. I recommend also purchasing the MVA6005 reservoir accessory which makes bleeding brake and clutch systems easier andless messy.

So I looked all around for hand vacuum pump and this is the one I settled on.It’s fantastic. BUT!!! Like other folks have stated the handle can and will pop out of place. The reason for this is two fold in my opinion.1. Slow down when you’re pumping so the piston inside of the device can pull the handle back out. This is a hand pump, if you try to pump too fast the piston will not go back into place by the time you’re wanting to squeeze again and the handle will pop off the pivot point.2. The design could for sure be updated. By either adding a pin or something between the handle and the main leverage/pivot point. I have a feeling though that adding something like that might make fixing it harder. The pin that connects the piston to the top of the handle really digs in, and eventually will need to have to be fixed due to wear. Put Teflon or graphite on there to reduce the wear there...but if they used compatible metals or secured that pin at the top better it may also last longer.

I bought the hand pump only because I was replacing a previous one. I had the plastic and the previous metal ones and this one looks and feels like better material. The gauge is easy to read for old cataract eyes and it swivels for positioning to read. When I opened the package I thought the gauge was broken and bent back. Just a scare because It's made that way. I have only used it once but the switching valve from vacuum to pressure is much better than the past ones and at low pressure and vacuum (1-2psi and1-2inhg) the needle moves instantly when plugging with your finger. Needle does not jump around when tapping on gauge. It is solid on the reading so if testing for leak down you don't have to decide if it's the gauge or an actual pressure change. That may change with age.

I have wasted my money twice on plastic vacuum pumps. This one is clearly superior to them. It has relief lever to release pressure or vacuum. Dual purpose. Vacuum or Pressure. You can move the gauge 360 degrees.

I ise this for working on 2 cycle engines, mainly Stihl Eco and Husqvarnas. It doesn’t come with a small enough nipple so I had to order that from Stihl.Pros:•It’s a great tool and is serviceable.•The price is much less then a dealers gage.Cons:•When pumping it you’ll feel a bit of a grind inthe handle hinge. There isn’t a bushing there.• The dial is at an angle and swivels easily.Both cons are irrelevant when compared to the quality of the tool. Just felt they were worth noting.
