First MB Brake Job
I'm getting ready to change the pads on my 99 E320 for the first time. I've done this on my Honda, so I understand the general procedure.
I've been searching the forums and here's what I think I need:
1. A torx bit to remove the calipers
4. brake paste
5. Anything else?
Random questions:
Thanks!
I've been searching the forums and here's what I think I need:
1. A torx bit to remove the calipers
- what size will I need? T40?
- do I want to remove the bolts or simply loosen them? I've seen different recommendations in different posts.
- what brands do people like?
4. brake paste
5. Anything else?
Random questions:
- Do I need a caliper tool to compress the piston or can I use a C-clamp?
- Are there 2 pistons on the rear calipers? If so, is there any special technique for compressing them?
- People seem to recommend autohauz for parts. Are there any other places I should consider? Any reason not to go to the local Carquest or Autozone for pads?
Thanks!

Hex bits and sockets for my 99's calipers. C clamp worked to compress piston for me. Pagid pads were OEM; have rubberized backing factory applied so paste not needed.
There are 3 wear sensors (both fronts/one rear) if all need to be replaced.
Will prob need hunk of 2 x 4 and 3lb hammer if replacing rotors too.

Diy
at top of forum also on benzworld.org w210 diy section.If your rotors are mirror smooth hand sand them in a cross hatch pattern on both sides with 140 sand paper,and then wash dust off with brake cleaner. then follow break in procedures provided with pads.
Work safe,use jacking points,jack stands,chock wheels,etc.

For Posterity
1. I got Pagid pads and MB wear sensors from the local CarQuest parts shop. The old pads that I removed from my car were also Pagid. A set of fronts pads, four sensors, and a can of brake cleaner was ~$70.
2. I needed a 7mm hex bit to remove the calipers. Sears had a small set of bits on sale for $20 and I picked up a cheap compression tool for $10.
3. I didn't bother with brake paste
4. Pay attention to how the caliper spring is installed. I put it back incorrectly on the first side and had to pull the wheel off again to fix it.
5. It looks like the rear pads are going to need replacing soon. On my car, there is only 1 rear sensor (on the passenger side).
6. I asked about loosening -vs- removing the caliper bolts based on info I read in another thread. I'm not sure why they recommended not removing the bolts unless you plan on lubricating them. They just slip into a rubber boot to keep them protected from dirt and salt.
So, 2.5 hours and $100 to change the front pads (and rotate the tires).

spend about $10 and get a caliper spreader tool. much easier and quicker than a c clamp. fits inside between the caliper and piston and just crank it down to push the piston back in.
x2 on the caliper spring installation. pay attention!
