Hello chaps / Chapesses

 

During Xmas holiday bike service noticed that the Rear Disc on me 2005 900er is severely uneven. Lots of ridges all around the contact surfaces.

Never noticed a lack in braking performance before I parked it up in December and there is loads of meat on the pads (which have the corresponding groves in them from the disc)

 

Use the back brake with normal ratio of application (dry conditions 75% front / 25% rear and in the wet 50% front / 50% rear)

 

The question is what replacement part would you recommend,

 

1. OEM from Fowlers or some such supplier at premium price (£180 odd)

2. Wemoto Premium EBC (£80 odd)

3. Wemoto Budget (£50 odd)

4 Flee bay -  £30 jobby.

 

Are the bolts a right chew to get out and would you recommend getting new ones with the disc.

 

I cant see me getting back on it till the weather turns so no great hurry to sort out.

 

Cheers in anticipation

OEM fur sure.

Not sure about 9er bolts but probably made of cheese. Correct fitting implement, heat and monkey pith should help.

I usually leave grooved discs if the minimum thickness is within spec and they pass the mot. You get slightly more braking force from a grooved discs due to an increase in surface area. If the pads fit perfectly and the caliper slides freely then there isn't going to be a problem.

Cosmetically some people might baulk at it though

If you do decide to change it, get some heat on the bolts before trying to move them. They're Loctited in at the factory, but a bit of heat melts the Loctite and they come out easily. I think I put a Brembo on mine when I replaced it, but I can't say I'm impressed by the quality of it though. I'd go OEM if I replaced it again.

I've put an EBC on mine and it seems as good as OEM over this winter.

+1 on the heat treatment - a couple of minutes with the heat gun and a decent allen key and all the bolts came out easily.

I'd definitely avoid ebay. Likely to be a cheap Chinese disk that will be more trouble than it's worth. Cheap Wemoto is probably similar.

As all above but don't be intimidated by applying heat. You only need a bit of warming , not glowing cherry red. I usually apply what I think is enough pressure on the bolt with the appropriate Allen key, then warm with a heat gun. You'll feel the loctite give up and won't have overheated anything.

Might be worth cross referencing the part number...I know the 850 rear disc was the same as the old FZ600. It could save some money

Wow - Thanks for comprehensive feedback.

 

Before jumping in I will check thickness with vernier and pay attention to braking performance when I get back on it in a few weeks time.

 

When refurbing rear wheel a few years ago, fitting new bearing and respraying it - I decided to leave the disc on as the first bolt I tried to undo was solid and I thought it was going to shear. Heat sounds like the way to go.

 

Thanks Gang much appreciated

When I got my mk1 the rear disk and caliper came from a 600 Genesis I had collecting dust......So it sounds like the same disc fits the 900 ?  Different calibob though

When I was doing my MK1 850 I had to get the disc off to repair two threads (one missing bolt head and one part drilled out but given up on- not by me) I got new bolts and tried the old welding a nut to the bolt heads and spannering them off welder was a bit tired and only got one out and usead six nuts.So all I did was build up a weld line acrose the head of the bolt, the bolt was now cherry red and all I did was get the mole grips out gripped the weld ridge and they undone a piece of wee wee.Protect the disc If you need It.

I've replaced a front Disc with one from Wemoto
No issues with quality etc stops the Bike etc

Being a Scotsman ( Tight Fisted ! ) it was probably the cheaper
of those on offer
So just because it's cheaper don't rule it out

i have three wavy disks on my MK1 none are major brands and all work efficiently with even wear and no judders and i have had no problems  - and surprising that chinese space rocket made it ok - given all the crap they make

Do you mean that one that broke down? Seriously I have a lot of Chinese stuff but most of it is cheap tat. Although a lot of Premium phones now are made in China - Huawei, HTC, honor, etc.

Point is you get what you pay for - usually.

Hi Chaps / ess,s

 

I know its a little down the road since this was started but i eventually got the rear disc changed in January this year. I opted for the Wemoto EBC option at £80 or so.

 

Had right job getting all of the bolts out with one being particular difficult (ahem ! Stud extractor required as bolt snapped off).

 

Any hoo - everything was Boo tick until about May when i noticed feedback coming through brake pedal when it was applied - now it is pretty bad with the pedal pushing my foot up and down when softly applied. 

 

Warped disc would you believe.

 

It did pass its MOT today regardless of this as braking performance appears unhindered.

 

WISH I HAD GOT OEM !! Bugger

Ooh - Never gave that a thought Dappers - Will get a look at it this weekend - I had to put new rubber boots on to the caliper slider bolts when i done the disc - got them from Wemoto when i ordered the disc but one of them was split when i got it oot the bag - they sent me another which was OK - but it might be worth a look at them again - just to be sure. 

 

Cheers me dears.
