STUCK CALIPER PISTON

No - but the zx7r forum says they will bolt straight on.

I’m assuming the four pot nissins remained the same throughout the bandit model run e.g. from 95 to present - so I won’t need to get a caliper from a specific bandit 1200.

I’m really pi1ssed off now - just want to part ex the 7r.

I’ll phone up a suzuki dealer/parts specialist if replacement nissin four pots will fit any bandit model from the early oil cooled ones to the latest water cooled ones and if they also fit the 7r then there shouldn’t be a problem in getting a set off ebay.

The 2nd gen Bandit 1200 introduced in 2001 changed to the six pot Tokicos.

Having had them on a ZX-9R I reckon you’re correct in looking to replace them with some 4 pot ones.

Didn’t you recently rebuild them ? I think I remember you talking about how expensive a full set of seals cost? If so, I’m surprised they’ve seized up so soon.

Hi Pat,

The tokicos seem to be notorious for seizing up at the drop of a hat - my rebuild doesn’t seem to have done me any favours - most people are happy to see the back of them and put four pots on.

Thanks for the info - hopefully i’ll see some affordable ones come up on fleabay.

Part of me wants to take the calipers to a shop to see if they can pop them out but I’m convinced they are absolutely jammed and it will be a waste of time and money even trying . . . :frowning:

Take em into ER on your way into work tomorrow? If they are buggered Mick prob wont charge you anything for having a look. Open from 830 get there a bit before.

Thanks mate - but I’m not in town this week - so maybe i’ll visit somewhere in surrey/hants.

I totally agree with this 7R rider on replacing tokicos:

  1. Go to your bike
  2. Rip off those crap 6-pots
  3. Throw in bin
  4. Replace with Bandit 1200 (1996-1999, mk1) Nissin 4-pot calipers.
  5. Rejoice, for your task is complete

They get rid of the spongy feeling, excessive lever travel and excessive brake fade- I’ve no idea why the stock calipers are so crap, but they are. After researching this extensively, it seems that Nissin spent a lot more time corrosion-proofing their calipers, whereas Tokico just played with their balls to pass the time.

Completely 100% bolt straight on, if you’re using braided lines you might have to change banjos for ones with a finer thread (Nissin runs a slightly finer one than Tokico)

They’re centred to the disc, 90mm spacing between mounts, and they work.

I’ve spent about 5 years, 3 sets of discs, 10 sets of pads, new caliper seals, 2 different sets of lines and countless fluid changes, just to find I should have got rid of the 6-pots.

pretty much sums it up … :angry:

if you can’t get the pistons out, take the calipers to OMC and matt’ll let you use his caliper removal tool. it’s amazingly easy!

also, you can get them in their parts cleaner and scrub them clean properly.

The 6 pots on mine have been great since I gave them a full rebuild with rubber grease on the pistons. I do know they can gung up quite easily though, I’ll swap to the 4 pots when they start to play up I reckon…

@ninja junkie you can fit the bandit calipers, but a better 4 pot caliper to go for are the 4pot tokico’s fitted to the gsxr600 SRAD’s and the TL1000S much better caliper and about the same price second hand.
bear in mind that these calipers will also be at the youngest, 12 years old and will need probable cleaning/new seals. however once they are done they will be much better than the 6pots and require less maintenance

Thanks fellas - yeah - hopefully the bandit calipers will be much better.

General consesus seems to be that 6 pot toks are a pain in the arse . . .

Now I’m worrried that the piston sticking incident might have cause the pads to score the discs and result in an MOT failure - I’m going to take the front wheel to the mot tester to find out if he’ll pass the discs or not . . . :frowning:

Didnt Shiver fit the r1/r6 (2005 r6) gold pots onto his gsxr? Does that mean that’s another option?

Mate - these are proper stuck - they are wedged right in so there is not much space behind them to build up serious pressure - I’ve also read threads where people with proper stuck tokicos have binned them because not even compressed air at 100 psi will move them.

I did but this can only be done on radial calipers

You can get adapters eg:

Ah spacers, ok. But an adapter like that? I wouldn’t. Not when its brakes.

I assumed the zx7r was also radial.

Ooooh they look smart

Nothing wrong with running adapters. I did with my sv using 6 pots

take the caliper off and leave it to soak overnight in paraffin, that works on my cbr rear caliper as they regularly seize up on a 'bird,

Yeah - I’ve had a go wtih penetrating oil but paraaffin might to the trick - thanks.

Is this a front calliper on a 9 fella, cos if it is… use some mole grips, screw the damage and you can have one of the pistons Ive got kickin round hte garage… seriously…

Thanks mate - really appreciate it.

I’ve got some Nissins arriving from a breakers so if that works out the Toks are history . . .

If the Nissins don’t work out I might be in touch!

Thanks. :slight_smile:
