Sorry to dig up an old thread...I want to make sure I am understanding this thread correctly. I have a Motive Pro Bleeder and have used it on a couple different cars with good success and have never bench bled the MC. I will be replacing the MC on my '99 this weekend. Can I assume that there is no need to bench bleed the MC if using the Motive Bleeder and just flush/bleed and fill the the entire system after replacing the MC?
On a separate note related to the other question I had regarding what I though was a engine vibration due to a possible vacuum leak is definitely not the case. I now have a bad drivetrain vibration. Really bad at 65MPH and above. Crawled under the truck with a pry bar to check the universals. Couldn’t move any of them, but I still wonder if one or both could be bad at 300K miles. Jacked rear wheels off the ground and ran up 70MPH. Still had the vibration.
If you are going for a full fluid replacement get different color brake fluid.
Could still be u-joints... Had a similar issue and even though I couldn't find any play, replaced the rear and it went away.
These are easy to make. I made one from a very inexpensive pump sprayer from Lowe's. I took off the handle just leaving the hose. I purchased a brake fluid reservoir cap from Toyota. I drilled a hole in the cap and hot glued a brass fitting into it. I then put the other end of the fitting in the tube coming off the sprayer. I zip tied the connection tight around the hose end and the fitting. Now, when I am going to speed bleed my brakes, I add clean fluid to the sprayer, attach the cap (and tube) to the reservoir for the brakes and put a big zip tie around the edge of the cap to hold it in place under pressure. Pump the sprayer a few times to build pressure and then start bleeding the brakes. It is quick, easy and cheap!
