Brake project
« on: November 30, 2003, 19:10:38 »
I am getting ready to replace the rotors (4), pads , flex brake lines and new brake fluid.  Is there any special tools or tips that will make this job go easier?  I am using the same wheel berrings. I dont think I need to rebuild the calipers  or should I ?
Any help would be appreciated.
Thanks
Larry

Larry,

I did the front rotors on my 230SL (drums in rear) a couple winters ago.  I suggest replacing the rubber components in the calipers.  There are seals inside the cylinder walls and external seals that keep road grime out.  These are very important, in my opinion.  While the pistons (some people call them caps?) are out of the cylinders you will want to examine everything for rust.  I had to replace my pistons.

You could probably use brake line wrenches.  They are open end wrenches that are almost box end.  They have a small gap that you slide the brake line through, then you move the wrench up on the fitting that you need to turn.  This gives your wrench more contact area, almost 6 complete sides, on the fitting.  I can't recall the sizes you'll need.

Examine your bearings closely.  You may be able to use the same ones, but make sure you clean them out with solvent and examine them closely.  Dry them well and repack with new grease.

To help prevent that high-pitched brake squeek that happens when not braking, there is a lubricant you place between the pad and the piston.  When not braking, the pad can vibrate and squeek against the piston.

It's good you are doing the flex brake lines.

Best of luck!
