One of the most important points in this video, ask me how I know, is to leave the master cylinder cap loose!! Otherwise you can pump forever and never get any fluid through the lines! Also, I had much better luck with the little pointed adaptors that just stick in the bleeder. And, I found that a couple rounds of teflon tape on the threads of the bleeder works better than grease, and not as messy. :) Good video and great product! I think I am going to add a magnetic hook on mine for some hands free help. ;)
I been using mighty for years do it right it works great. Old school always grease the brake fittings. I had 3 uncles mechanics gone now taught me old school ways……..
Well, once I’m done bleeding the big brake kit on my 2015 Infiniti Q70L. I will come back and leave you all a review on how it went. I’ve had this mighty vac for a while and purchased it at O’Reilly’s for a great price. I have used it to bleed my clutch on my 2006 Pontiac GTO since I do have a speed bleeder line for the clutch assembly.
I have a question. There is a debate about the hose in the bottle. Some fill the bottle with an inch or two of brake fluid to suck fluid back into the tube eliminating bubbles. Others use no fluid as you did. I have always used some fluid in the jar which is correct
Hi I just recently bought this pump and for whatever reason it is able to pull vacuum if i hold the handle down but when i release the handle the vacuum restores to no-vacuum - not sure what the issue is - i have disassembled and cleaned the entire unit and no signs of brake fluid or debris. Seals all look new as the unit is brand new with the exception of 1 time use which at that time it worked great - but no brake fluid has been in the gun
I bought one about 15 years ago through an advertisement in the back of a magazine. I tried it multiple times and I couldn’t get it to work. With shipping about $60 wasted. I threw it in the trash can. I’m not making this up.
This needs to include a tight clamp where the hose slips onto the bleeder valve. (Please don't suggest customers go out and find/buy one somewhere.) Nothing I tried -- the suggested grease included -- prevented air from being sucked in between the hose and the bleeder valve. It's now sitting on a shelf, money and time wasted.
What I did was slip the hose onto the bleeder valve and then install a zip tie around it so there is a very tight seal. Hopefully this helps and prevents your tool from just sitting on the shelf as wasted money. Have a good day.
I did that as well, but air still is sucked in via the valve threads. It's why pressure to push out the fluid and air works, and why sucking it out fails.
Should never have to use grease on threads of the bleeding valves, there is good chance the grease residue will get into the the brake lines & will contaminate the brake fluid, a bleeder valve should only be opened at max 1/4 turn only, as for using a hand pump is something I never use I am old school no need for these vacuum pumps.
I bought this tool thinking it may help me. Well, it didn't. I tried all that was suggested, even greasing the bleeder. Nothing worked so I bled the the bike the old school way. Harbor Freight will get it back.
Greasing the threads of the bleed screw has been an old-school method for years to prevent air bleed by of the loose thread. Many have also opted to using a small amount of thread tape or paste instead. any of these options can work to provide added sealing. ~ John
