Perhaps you can use them for service exchange?

Eight years ago,
I bought reconditioned calipers from a local motor factors, their suppliers were happy to accept bigger calipers as exchange items.
I think the recon calipers were about £80 for the pair.




Ian.

Thanks for the offer Steve, but I already have the discs and brackets, bought from trackerjack himself a couple of years back.

I think I am right in saying that the main difference in the calliper for the 260 mm disc will be in the carrier to space it further out, so I expect a recon calliper set would come without the carriers I'm afraid Ian.

I'm struggling to find a pair of sierra callipers with the carriers.

Does anybody know which KA calliper does the job? As far as I can see, the ones for the 240mm disc seem to have a smaller 48mm piston.

Cheers

Tom.

The ka caliper from any with the vented 239mm disc will have the 54mm piston so its quite easy really. I have 2 sets of ka now for my 2 sprints

Tony

Sierra discs were all 239 mm apart from the odd non vented (we ignore) and all Sierra x series including 4x4 were as you say 258 mm and if you put the wrong calliper on it is immediately visible because the pad doesn't fit.

Are these kits still available?

Puma calipers do indeed have the 54mm piston and Puma pads are HUGE compared with the Ka ones, (though still fitting the Golf disc) but the Puma carriers are for a 258mm disc.

I assume the puma pad/calliper doesn't fit the KA carrier then Steve? That would just be too easy.

Thanks for the info.

Tom.

Are these correct? says mk5 escort, 240mm disc....

I dunno mate, I haven't got a Ka carrier to try! TBH I wouldn't be surprised either way!

These have a different design of carrier with only one big slider at the top. Whether such carriers will fit the TJ brackets remains to be seen.

Steve

When I fitted my KA ones to the carmine sprint I fitted mine on the front not the rear as most seem to do

The hose is a braided one I made up and has a metric thread so I changed the brake pipe to suit as they were being changed anyway. This gives a more natural pipe run in my opinion

Tony

I'm sure there is a reason for not doing it that way Tony, blessed if I know what it is though!

Steve

TBH I'm not 100% but I think it's to do with flexibility in more than one direction, and thus avoid wear from repetitive flexing in one way.

I know what the reason is Steve. When first mocked up (wheels at full droop, jacked up on the chassis) it all looks fine until you pull the hubs round to full lock. Then the bottom caliper to bracket bolt (with the rubber sleeve and the 7mm allen bolt inside it) touches the lower arm! Seemed alarming at first but when I jacked up the lower arm slightly it clears. Because of the angle of the lower arm a tiny amount of upward lift makes tons
more clearance. Worst case scenario is full lock and full droop and if im flying at that angle I think I'll have more to worry about than a caliper bracket .
The brake pipe routing is as factory so no need for extra pipes etc.

Its a good point Mahesh but in the pic its straight looking on full lock. It then goes into a U shape on the other lock with no fouling. All flexies have to go through repeated movement and in the first pic the rubber flexy is the actual Ford pipe and is located in a similar position on the Ford, however I deemed it a tad to long and could flap a bit more hence the braided hose.
