K1 Naked Rear Caliper Pad Spring

[eifionglyn]

Hi,

I was giving my calipers a clean on my K1 naked that I've owned for 6 months and noticed the rear pads could do with changing, however, one of the pins is firmly corroded in place so will have to take the caliper apart just to change the pads. While I'm there I might as well do a full rebuild, change the fluid, seals etc.

So before embarking on this I have a look at the Haynes book. Apparently on the rear caliper there is meant to be a spring does something - hold the pads away from the disk when the brake is not applied? - anyway said spring is absent from my rear brake caliper, so if it's meant to be there I'd quite like to make sure it is.

Do I actually need it? Rear brakes work fine, quite effective and don't drag.

Anyone know where I can get one? I've searched the usual online parts shops, sportsbikeshop, M&P etc, and ebay. Lots of brake parts, pads, seals etc but no springs come up.

Thanks

I can't remember the function of this spring, I think it holds the shim to the back of the pad?

You can get one here

Part number is # 59143-16700

Get some stainless pins to replace the OEM ones & grease them where they fit into the body of the caliper

Brilliant, thanks for that. :)

Turns out from the diagram that the the shims are also absent from my caliper.

you dont really need them as they are just anti rattle springs but better being there than not. there should be 2 of them.

good luck getting the pin out, most people resort to drilling the end housing and punching them out then drill another hole in a new pin for another R clip. try drilling a smaller hole than the diameter of the pin then using a nail punch first, once it moves then it will come out by twisting it with moles.

when rebuilding your calliper make sure that the seal recesses are well cleaned out of 'furring' and then use RRG to install the pistons and seals. do not use brake fluid to install your seals.

the only place copper grease should be used is on the pins and not on the back of the pads.

As above :cool:

Hmm, 2x Pins, 2x springs, 2x shims, pressure + dust seals. Plus a load of hassle getting the seized pin out. Getting close to the cost of just buying a refurbed caliper and have done with it.
