Yea, I saw rookie techs and shadetree mechanics do that. Part of my job as service manager was hiring a new tech, qualified or a rookie, and helping bring along the rookie and also assigning him to a qualified tech as his helper to learn the proper way for repairs. I saw lots of ASE certified techs that could not tighten a hose clamp correctly.

I was totally embarrassed that I had done this. I hate it when I have to admit that mistake! On the other hand, I've had other shops make potentially life-threatening mistakes and not own up to it. At least I knew I had a problem, admitted it (to myself at least), and fixed it.

Part of accepting a problem has to do with admitting the mistake. People are human and will make them and if so, admit it, apologize if needed and make it right. I told my techs that if I asked them a question about a repair or a diagnosis and they could not answer in the affirmative or negative with absolutely 1000% certainty, then find out why. I never accepted the words: could be, maybe, might be, hope so....etc. Those words or phrases leave an out for the speaker to say I never said for sure. If the tech or yourself needs more time to be sure, TAKE IT. I would never fault a tech or a member for that. If I had a tech winging it I would remind them all the manuals or software available to help with the work or diagnosis. Use that shit. I had a customer one time say he did not want a tech to work on his car because he saw him get a manual out. I told him that I would fire that tech if he didn't get the manual out. I then went in to my pat answer to the customers.

"Doctors have it way easier than techs who work on vehicles. They work on two models and the models talk to the doctor. The tech works on way more years and models and they don't talk to the tech". That always always worked.

That’s the one. You will love it @donjetman - easiest brake bleeding you’ll ever do. I tried the vacuum ones, what a PIA they were. The Motive is awesome.
Edit: I thought you had the same one @donjetman but that’s for Eoropean cars and is a bit different. The one that Ron posted is the one I bought and has the adapter for GM.

Yea, that kit I posted comes with the 1108 adapter and is the right one for my rig. Plus you don't need the air compressor fired up like some of the others. The hand pump for pressure looks easy as hell. The only thing I don't like is if I would have to buy other adapters for other vehicles if I am working on a friends vehicle. I would just make my friend buy the adapter and leave it with me. LOL!

I would not let a brake fluid flush go past 50k miles. Most vehicles qualify for maintenance under the SEVERE schedule.

Thanks for the link Ron. I just ordered that bleeder. Unfortunately I will have to spend more money to get the adapter for our Explorer. Last time I looked into the pressure bleeder, the prices were out of my budget range. It seems as if the costs have come down.

Quick couple of observations. Technically brake fluid is supposed to be changed annually because of water. But who does that?
Crap will eventually move through from the caliper to the reservoir. Hot fluid moves up. It’s how once clean clear brake fluid eventually gets discolored in the reservoir over time. Much quicker if you cook your fluid on the track.

last, I did a bbk swap and brake soft line to longer braided lines on my Chevy prerunner.

bleeding was a nightmare. I assumed that because I had a vacuum bleeder that ran off my air compressor, that I would be good to go in a matter of seconds.

I sat for an hour. And then got the missus Into the drivers seat to go the old fashioned way. Nada.

then I finally pulled out my autel and went through the abs bleed program.
Ran that twice to be sure and hard as a rock.
I hate that you need special computer tools to do basic maintenance.

even worse, if I ever decided to get rid of the abs system in the prerunner, and go manual brakes, then I have to go stand alone for the ecu because the bcm will nanny everything

You wouldn’t.... lol

other people would.....:)

That's what happens when you talk about other people. LOL! Lots of people believe in "breakdown maintenance" instead of "preventative maintenance".

My dad taught me, "Maintenance pays and breakdowns cost".

If you live in mountainous areas where you might ride the brakes more than normal, that heat transfers to the fluid and breaks it down and it also gets moisture in it. DOT 3 fluid is hygroscopic and loves to absorb moisture from the air and since brake systems are vented, it allows that fluid to draw the moisture in the air into the system. Silicone brake fluid is not effected the same way. It also handles higher heat temps when braking as well. If I am not mistaken, for going on years back, all motorcycle brake fluid was silicone fluid. The year that most vehicle manufacturers switched is a time I am not familiar with.

I’m in the process of installing a Wilwood BBK on my 08 Silverado and they sent me 24 oz of their “570 racing” Dot 3 fluid which says is a high temp with a minimum boiling point of 284 f. I already had 24 oz of it from the first BBK I bought from them so I guess I’ll do a complete flush. The Motive will make it easy. The truck has about 60 k so it’s time.

It seems like a silly question, but it happened to me last year after 30 years of doing my own brakes....

Did you install the correct side caliper? A right caliper on the left side may physically fit, but the bleed screw will be on the bottom and you will never get the air out.


Local parts store grabbed me two new calipers off the shelf. I noticed both same PNs. Assured me that it was correct.

Would not bleed. Limped it to local shop.

They let me know I was sold two driver's side calipers. They contacted local parts shop who they also deal with routinely. Just paid for labor.

It happens.

I use a Motive pressure bleeder. I have flushed the entire system more than once on a couple trucks since buying it and it is amazingly easy, a one-person job. Well worth it imo.


What PSI so you keep the container?

I looked at a video about them and to first test for leaks in the Motive system you pump it up to 10 psi and then if is ok it said to add the fluid and then pump up to 15 psi during usage.
