[quote author=Gnasher link=topic=26278.msg317519#msg317519 date=1594115374]has caused agitation of the fluid by shaking, over pumping or just bad practice, you'll get micro bubbles.

Contextually I don't grasp how or why would someone would do this, the ABS unit would be bolted to the bike. But with regard to over-pumping, how exactly..?

• Just bleed the system as normal but slowly and deliberately, gravity is your friend here, so is a good vacuum bleeder with experience and skill. 
  
• Brakes aren't DIY if you don't know what you're doing, many think they do until they get on a bike with proper bled brakes.
  

• I have one of those, but either I didn't take enough time bleeding the brakes or need to understand exactly how and where I was using it incorrectly.
  
• I assume your referring to ABS-based bracking systems? as non-ABS is DIY imho and should well within the scope of most competent home mechanics.
  

And regarding mechanics that say they know how to bleed an ABS systems, how do we tell they actually do know and aren't like in my 2x instances where they  didnt.[/quote]

Mate the questions you're asking are exactly why brakes aren't DIY.  I'm sorry but most home mechanics are just getting away with it, I'm not entering into an argument here, or trying to disrespect people.    I've seen hundreds of examples of DIY on brakes and it's frightening.  :eek :rolleyes

I'm happy to help but too a point, what you can never underestimate is, experience and skill, that can't be learnt via internet forums. 

If your brakes are spongy after they've been worked on by a professional who you've paid, take the bike back and give him/them an opportunity to correct the work.  If they refuse demand you money back, don't go trying to sort it yourself.
