Has anyone experienced their larger brakes fading?

I had a not so nice experience as I was racing a motor bike the other day, came to a roundabout and the brakes decided to fade. They have never done this before, always thought they had been pretty cr#p but this convinced me. Luckily there were no cars coming & I got round no problem but had to stop all the larking around. I have got the 320 or 330mm large discs with the spacer on the calipers coupled with carbon pads. Do you think I need to upgrade the calipers now?

It's possible you boiled your brake fluid - what are you using ?

Using dot 5.1 synthetic I think so thought it would have been ok.

When was it last changed?

5.1 has quite a low life span and should be changed every year iirc

It was changed on the last service which was just over a year ago but only about 3000 miles. Looks like i'm changing that this weekend.

Well it's a cheap change anyway.

 

On a slightly dafter note. Does anyone know of brake fluids that are coloured in anyway ? I was bleeding mine at the weekend and because the old stuff had hardly discoloured at all it was very difficult to tell when the new stuff was coming through.

My brake fluid is blue!

 

called super racing blue, or something like that. HTH...

Hmmm, perfect for my car !!!

Are the pads well worn/ not much meat left?

Quite a lot of meat left so thats not a problem.

get all the pads out and check none are seized or sticking , this may well cause poor braking

 

andy andy if you know the amount of fluid in the systym just drain out the amount specified and then you should in theory have new fluid through out, if the fluid is clean anyway its normally a testament to the owner :duffer:

Yeah, I know but I never measure what I take out, the catch bottle is smaller than the new bottle etc. Also I have to bleed it at 10 different points so it's much easier to see it change colour at each point.
