Review on 🚗 Optimized Automotive MV8000 Tune-Up Brake Bleeding by Paul Lee

A professional mechanic friend of mine recommended this item to me. This cut my respect for his reputation in half: the first thing I did out of the box was put the parts together and do a mock test: I couldn't create a vacuum. The rim of the old brake fluid reservoir did not close. I thought the o-ring was missing. I carefully studied the instructions and came to the conclusion that there are no gaskets in the kit. In the end I tried all 6 orientations where the 4 ounce container snapped into the lid with the vacuum IN and OUT ports, found 2 positions with this tightness and marked the best orientation with a permanent marker so I could she could find next time. day for a wet run. The manual vacuum pump creates a good vacuum. But the devil is in the details. Additional problems prevent the seemingly excellent design of the vacuum bulb, piston and valve from being useless. All in all I pumped several liters of high quality (expensive) brake fluid through this device. My wasted brake fluid cost is more than the original price of this unit. First, the biggest design issue with this device is that it only has a 4-ounce "collection bin." When you need to quickly pump gallons through a motorcycle to get air bubbles moving up the brake lines, it's a heck of a lot to stop when the flow has almost emptied the air from the system to have the bubbles rise vertically again be able . Brake hoses to the steering wheel! The biggest problem is that the small collection vessel requires you to pause your progress every minute or two to empty the tank again. There can be issues with this device, I have provided a bulleted list below. The vacuum trigger has a trigger. And I mean a hair trigger. If you hit it, touch it to the side, try laying the device down on something while you refill the steering wheel's fast-draining brake fluid reservoir (which requires attention about every 15 seconds), the vacuum is released. At first I thought "no problem”, but it turns out that when the device releases the vacuum, the air rushes back into the caliper's working cylinder. So you have to grab the vacuum pump in the same place as the vacuum trigger. My advice is to remove the trigger with snap ring pliers. You can easily pull the valve drive end without the giant trigger lever that someone (probably the marketing committee) decided to put in. Here is a list of the issues I've encountered with this product. Maybe there is a better product from the same company, or maybe I just got a lemon. I can usually trust the advice of my mechanic friend, but not the WRT of this article. Its problems include: Poor vacuum seal at the lip of the sump; It's hard to avoid the vacuum trigger; The rear handle of the vacuum pump falls off during use. (see photo); The soldered "dial" for the vacuum gauge fell off. (Maybe the worker forgot to glue it?); The white spot on the side of the vacuum gauge frame (pictured) is due to contact with DOT5.1 brake fluid - the most benign. One would think that a tool designed for use with brake fluid would not be immediately destroyed by brake fluid on first contact with a small amount of it. The other side of the originally black bezel is mostly white; Neither 6mm soft rubber fitting sealed my lubricated 6mm exhaust valves well; The supplied vinyl tube was crumpled up in a tiny compartment in the corner of the box. Although I stretched it overnight before trying to use it, it curls up when you try to use it, knocking over a miniature collection jar and pulling the bleed valve at the worst possible moment. Every time this happens the system re-enters the air that was there when I decided to use the "Pro-Tool" to remove the sponginess that was left after using the brakes with vented from my homemade bottle of Gatorade. If that infernal trigger blows air back into the system, you'll have to start over. A square piece of black plastic just in front of the vacuum gauge has fallen off the vacuum pump. I thought it would be a decorative end of the trigger because its hollow cross section is shaped like the cross section of a giant trigger lever. But I can see that the product photos don't have that decorative tip on the trigger, so I'm completely at a loss as to where it's coming from. When I say "fallen" I mean it fell out. I didn't hit him, I didn't drop the pump, nothing. I took it to another room to dry after cleaning and it fell on the floor. After 6 hours of trying to get this unit to work (and I'm no beginner - I've bled brakes before) the sun went down and I gave up. Complete FAIL. The brakes were much worse than at the beginning. They weren't even spongy. No participation. There may be more issues I forgot to mention about this wonderful tool, but this is as much of my time as I can afford making Jeff rich. Thank goodness I still have some time to get that POS back!
