Brake Flush Procedure

[bpossel]

Hi All!

I searched the site and can't find any info on flushing the brake system.

Can anyone please explain this to me or send a link to the procedure?
Should I buy a brake vacuum to do this and what bleeder plug do I start on, front drivers side?  Work from front to back?

Any advice is appreciated...

Thanks!
Bob

From what I've read, you bleed from the furthes wheel from the brake booster to the closest.  So on a Left-Hand Drive car, the order would be right rear, left rear, right front, left front.

Is there a bleed screw for the master cylinder?

Hi Rodd,
No bleed screw on the master cylinder.  It gets fed directly by the reservoir attached above it.

I've always had my wife pump the brakes for me while I do the bleeding.  The first wheel that you do takes the longest because of the distance away from the reservoir.  The rest are a lot faster because you have clean fluid already in the lines.

Make sure that you have plenty of brake fluid handy before you start.  I prefer Castrol.  All you need is a rubber tube to fit over the wheel cylinder nipple, a jar and a open end wrench.  It's great fun to watch the old yucky fluid come clean.

Regards,
Don

Contact www.motiveproducts.com. ask for the Mercedes Benz resivor bake cap for the bleeder and follow instructions.
I have found that you will have to remove the center rubber blatter that devides the two bake resivors and the screens. replace them with new or if ok place orginal ones back. I also found that Mercedes-Benz supplies new bake bleeder caps as well to put on your caliper if they are missing.
Good Luck And Happy motoring

Thanks Bob!

I ordered the Motive Power Bleeder on Friday from Apex.  Had best price and no shipping cost.  When I get it and do the flush, I'll update the site.  Also, thanks for the tip about removing the bladder...  makes sense!
