Caliper resetting tool# 34 1 500

[hawk20710]

Hi, Has anyone bought or made the BMW No. 34 1 500? If so could you send the dimensions in the forum so I can make this tool? Clymers says to use a piece of 1/8" steel to fabricate but it looks a little flimsy. -K-

That's what large flatblade screwdrivers and scrap wood are for.

Karl,

What-Ya-Trying to do?

I hadn't searched to see where that tool is used, but, when replaced my pads, I used the old ones and a C-Clamp to compress them, no problem.

I'm more of a "rigger" than a special tool buyer :)

if you remove the caliper, you shouldn't have any problem depressing/re-setting the "pistons" using your thumbs actually. It's a little easier if you take one of the old brake pads and a c-clamp, but even that's probably not necessary...save the cash and try it first

When I first purchased my LT, I bought that tool and the piston spacer. I may have used the tool one time and now just use a screwdriver on the old pads to retract the piston. If I am just flushing the fluid I will use a pair of pliers to push the pistons back in.
The spacer tool would be more helpful to hold one of the front pistons in while you are depressing the other. I am attaching some pictures and some measurements.
Piston Retractor:
1/4" bars
Outside space when open is 1-3/8"
Outside space when closed is 1/2"
Tool is about 2" square where it goes against the pistons

Spacer Tool 34 1 520
3/8" thick
1" wide
2-3/4" long

If you need any additional info, please email me.

I just pull the old pads halfway out and "lever" the pistons back. I did make some spacers out of a cutting board to hold them back for my brake flushes.


We don't need no steenking special tools.:)
