converting a solid disc rear brake caliper for a 2.6 omega

(1/3) > >>

Hi

I am sure I read a post on here, about being able to convert solid disc brake calipers, to use on a 2.6 Omega with vented discs. By splitting the damage vented disc caliper and fittiing the spacer from it to the solid brake caliper. So it will work on the vented discs.  If it will work is there any specific size caliper, for example off a 2.2? Also would the fact that the pistons off the solid discs are smaller, make any difference to the braking, when made up to fit on the 2.6? Also what refurb kit, would I need to get the O rings, for the spacer piece, when fitting in the solid disc caliper?

The reason why I am asking is that I am going to be doing some work on the brake system on my 2.6. When last I did some work on them, I wasn't really happy with how they looked. The bleed nipple has snapped level with the caliper on the one and it looks like a ease out, has been snapped in it.

Sorry for all the questions. Thanks in advance for any help.

Doctor Gollum:
There's four bolts to split the caliper, just go easy undoing them. You will also require seals to replace the existing ones, but you will need the old ones for dimensions.  ;)

Thanks DG for the quick reply.  I have found refurb kits including all the O ring seals for both the solid and vented calipers. Would I need the vented caliper kit, even though converting solid caliper to vented using the spacer, or the would I need the solid caliper kit?

Here are links to the different kits

Thanks again for the help.

Doctor Gollum:
Vented disc kit will be just right ;)

The only caveat is that you may also need the solid disc piston seals to allow for the different sizes... 40mm (solid) vs 42mm (vented).

Incidentally, the four small o rings are for either side of the two spacers ;)

Enceladus:
The vented 42mm bores vs 40mm gives you about 10% more braking force applied to the rear discs.

Is it that the problem you want to fix is that one of your existing vented rear calipers has a sheared off bleed screw that might have a broken extractor in it? Nearside or offside? Your request on the forum for a spare hasn't produced any result?

If so can anybody weld a nut onto the broken bleeder and get it out that way? Or recommend somebody who can?

Assuming you have a usable pair of non-vented calipers available then I suppose you could simply install a pair of solid discs to match. That might be cheaper and easier.
