How often should your ABS Actuator re-pressurize?

As it ages the re-pressurization will happen more frequently... Once it happens frequently enough you'll get warning lights. Once you get to the point you're hearing it re-pressurize every few minutes you can't safely keep going without replacing it with a used / new one.

 

That sounds pretty much like a description of absolutely normal to me.

I hesitate to write that, because some obsessive somewhere will read it and then panic if they hear theirs pump after three brakes.

It normally varies. Variables include how hard you brake, how much piston return the calipers have, how flat the rotors are, etc. The best answer is "about every so many uses of the brake."

But every 4 or so isn't anything I would obsess over at all.

 

about the same as mine. i don't expect it to be a problem for a long, long time
