When I bought my K-RS, I noticed a scratch, just above the RHS footpeg, which ran right across the hangar plate.

Last Wednesday, I discovered, the hard way that this was, in fact, a crack.

Motorworks have supplied a replacement hanger plate, so now, I just have a couple of questions...

First of all: what size Torx bit do I need (and why the hell have one Torx among a pile of hex bolts)?

Secondly: anyone got any tips, bearing in mind that I can be a bit cack-handed (a combination of clumsy and rough, for the colonials)?

Cheers!

IIRC the master cylinder is on that plate. So once you undo the top bolts, it will hang on the brake pipe. Consider also, the brake light switch cable. Can't remember what size Torx, but one in my Halfords set fits. Don't get frightened, it aint rocket science, just take care, work methodically & don't force anything.
When reassembling make sure there is a clearance between brake operating pin & master cylinder piston. It is common to find them over adjusted to lift the pedal, which causes sticking brakes.

I think there are four things to consider:

1) As mentioned above the rear brake master cylinder is attached to the hanger. I have not found a way of swapping the hanger without removing the brake line from the master cylinder - and therefore requiring a brake bleed.

2) The brake pedal, spring and bush need to be fitted carefully - the spring tension is quite high

3) When refitting the brake pedal ensure that the pin on the pedal which compresses the master cylinder piston is properly engaged before tightening the pedal retaining bolt. It is possible to distort the piston if the pedal bolt is tightened without the pin properly engaged.

4) As stated above ensure the clearances between piston pin and piston as well as pedal to brake light switch are set properly to avoid brake bind and potential rear end fires (as reported by at least one other)

It looks a simple job at first glance - and it is if the above is taken into account. I've done it twice!!

BTW you can get a really high quality set of hex keys and torx wrenches from Range - they are extremely good value. There is a store on Crompton Way Bolton.

I've never had a problem with this. Remove the peg plate and while holding it remove the two little bolts that hold the MC to the peg plate.

Did it the same as Duck, bit fiddly refitting it but does work.
Make sure you get the lever for the brake light switch in the right place.

Right, just tried a couple of things before I start the job properly:

The 2 Allen bolts undo easily - The Torx is a good bit harder - not sure why.

I have hit a problem, though: The 2 bolts securing the pannier rail aren't loosening - whatever they are fastened into is just spinning Confused - any tips?

Cheers,

There should be a nut on the back of that bold. 10MM I think

I thought so, too, but whatever it is appears to be circular, with no evidence of flats, as would be expected on a nut... Confused

You are quite right - and it can be a pain. If you're lucky, you can get hold of that bit with a long needle nose pliers.

The last time I had that apart, I set it back in there with some kind of glue - seems to be OK so far.

It's a bit of work, but you'll get it

When I get it out, I may actually secure it using a nyloc nut with a few washers to shim the nut out, so I can get a spanner, or socket to it, in future.

If you look closely at the nuts, I think you'll find that they are the locking type. I found that a box-end wrench works if you get it tight against the base of the nuts - unless a previous owner has rounded them off.

Well, sometimes I look at things and wonder... I mean, the "DO NOT TOUCH THESE!!!" screws on the throttle butterflies have been messed with, so little surprises me... Rolling Eyes

They're round from the factory... They were never hex nuts. And they are all but impossible to get to.

Hi Jim,

I guess I'll have to take a close look at mine next time I get at the bike.
I never had a problem removing mine and I've had to do it a few times in the last few years. Haven't had to undo the brake line yet.

Don - the Z racks for the luggage/panniers - not the footrests... thread drift.

Well... I've got it off - apart from one of the bolts holding the brake switch to the plate. Sad

It's probably never been removed, but it looks like it was never lubricated, on assembly. I tried to undo it ( quality tools ) with gentle but firm pressure... and the bit turned in the socket (I put it in carefully and made sure it was seated properly) - BUGGERATION!

Looks like I'm going to be doing some drilling (I'm already going to have to drill, cut, or dremel the bolts on the pannier rack.

Banging a sacrificial torx key into the bolt is not an option, the plate is supported by a bucket, to alleviate stress on the hose and I haven't got the skills to faff about removing brake hoses and bleeding them.

What a bloody awful idea to go fastening anything other than footrests to a footrest hanger plate - especially when the bolts aren't greased on assembly and steel bolts are being screwed into alloy.

God's flaming bogs, BMW!! Were your designers on acid?!?! Evil or Very Mad Evil or Very Mad

This is getting to be enough to make me sell the bike, once I've fixed it!
