thou rear caliper on 600

[midden]

Does putting a thou caliper on the back of 600 mean you can do sideway skids down the road.
I'm a heavy chap (though some may disagree  ) and i really need to push hard on the pedal for the back end to lock up, so the brake does seem feeble but nevertheless I still mange to come to an abrupt stop when needed.


Surely though this is how Yamaha intended it to be.


It's always been my understanding that most of the braking to stop the bike comes from the front and the rear brake really is only to maintain balance (if that's the right description)
So by fitting a much sharper rear caliper raises the risks of rear wheel lock up and means the rider has to consciously apply less pressure on the rear brake thus cancelling the point of the swap.

I disagree, even the likes of Mick Doohan used their rear brake on-track and from a road bike perspective if you're out in the rain using front brake only your chances of buying a plastic repair kit greatly increases.

If the standard 600 caliper is working properly it should be fine; however I'd say about two thirds of people don't bother cleaning their calipers regularly and so they become fairly useless as they gum up.
FZS1000, XJR1300 or YZF750, TRX850 & Thunderace rear calipers all have 43mm instead of 38mm pistons, so less effort on the pedal for more effect. I have a Thunderace rear caliper fitted & wouldnt go back to standard as 'feel' is much better

Ah ok so it's more to do with the piston getting dirty and not performing as it was designed to, rather than just being inadequate from the start.
I use my rear brake a lot through the corners so I think for that reason especially I quite like it's lack of locking ability

Yes it is easier to lock the rear wheel, especially with the weight transfer to the front, especially under panic braking, but the benefits outweigh the negatives. As riding is all a matter of confidence, fit whatever brakes and tyres you want so that psychologically you feel it is the best for you. Personally the thou caliper with soft pads has been fantastic for me even with the occasional skipping through partial lock up. Of course, with observation it is very rare to need to panic brake, but that comes with experience and skill.

got the standard caliper on the back but I wonder if it would be easier to not lock up the back wheel if it was a bit better. With more powerful brakes you can sometimes focus on controlled pressure instead of stamping on it.


Also I seem to remember you needing to move the pedal more with the bigger caliper so that might make minor changers easier to apply.

I had to put another rear calliper on mine as it was completely knackered, pads had rusted to twice the width and no amount of persuasion would get the pistons to move. I replaced it with one from the FZ1, two minutes with a dremel and mod done, works a treat. I have no knowledge of the original and the gazer is my first yam. I find the rear brake ok when I use it which is not very often; slow manoeuvres and scrubbing a bit of speed of if I over cook it into a bend.
