Hi folks!
Just curious what the group's opinion is on changing/bleeding brake fluid on newer street driven cars (i.e. CLK500 @2000mls/year) with ABS: 1) Yes, every 2 years or 2) I have never done it and my car drives just fine Also, how much different is the work with ABS, compare to our 914s? Just trying to get some education before talking to my "new" car mechanic. Thanks, (IMG:style_emoticons/default/beerchug.gif) dc PS: I know this topic/questions will be opinionated. |

Brake fluid absorbs water so yes it needs changed. I wait until I do brakes.
Mark where the level is before if you are not putting in all new pads and rotors. It's a balanced system, if you "top it off" it will leak out and eat paint later when you push the cylinders back in to fit new meaty pads. ABS cars are a PITA. With a 914 or other non ABS car you can use a vacuum or pressure bleeder making it a 1 person job. ABS needs either a pedal pusher or dealer electronics. Side note- if it says you need dealer electronics you might just need a pedal pusher, as being a dealer tech is a solo job. |

I found the vacuum systems work okay to an extent but I'd top off the system, open the r.r. bleeder and let it flow until the M/C level dropped considerably. All of this after I sucked the reservoir empty, cleaned it out and replaced with clean fluid, then started the gravity procedure. Then closed the r.r. and proceeded around the car in the correct sequence. This way I could do other work on the car or another car without babysitting the vacuum bleeder... saved me time and made me money! |
