Part numbers for brake caliper o-rings
 

Hi,

I have to rebuild the brake calipers on my airplane so I'm looking for a little help to find the part number for the caliper O-ring kit. This is a regular Cleveland brake caliper, does anyone have the number? Do the usual culprits keep them in stock?

Thanks, Pete

Here is a cut and paste from the e-mail last time I ordered some o-rings:

I ordered these (and extras for spares/buddies) from O-rings USA. Note that these are the Viton o-rings, which are compatible with both the "regular" hydraulic fluid and the higher-temp 83282 which I use. The Viton rings are better able to resist high temps and are a drop-in replacement.

The ring size you want is the -218, I think you can use either durometer of the Viton (V75 or V90). I'm currently using the V75s on my RV-8 and they work well.

The BN70 "Kit" was the plastic box full of every size o-ring that a lot of FBOs have. It's useful to have around.

Hope this helps.

James,

Thanks very much, that's exactly what I needed.

Peter

Also can find exploded view in 2006-2007 Spruce Catalog, p.230, or online. Spruce o-ring part no is 101-02300. Pls note that it is possible to install the piston backwards, not good.

that part number is not the higher grade o-ring. this is the older style. i've called and talked with spruce about this.
