Rear Brake.

[Paul Bryant]

I've been having a problem with my rear brake, what happens is that I'll be hooning through some hills and I'll loose the rear brake, the pedal just hits bottom with no brake activation.
Initially I thought I needed a Master Cylinder kit in it, but went to a Brake Specialist in town (Hamilton) today and Beaven tells me I'm boiling the Brake fluid :eek3: which did make sence cos if I cruise quietly for a while using only the front brakes, the rear brake comes back.
As Beaven (at Apex Brakes) said if it was the Master Cylinder seals, I'd have a constant problem, not just when I'm blastin through the hills.
He asked what brake fluid I had in there, I had no idea, but he gave (sold) me a bottle of Motul brake fluid which he says most of the sport bike Guys use and also the race cars.
If I continue to have problems, he does stock a higher boiling point fluid, but that was about NZ$120.00, US$100.00 a bottle (500 ML, 1.05 US Pint)

I've not changed the fluid as yet, but will report back after I've done a change and been for a hoon up in the hills.

Re the "Floppin gear shaft" thread, Whada ya sayin Scott ? "Especially since Paul thrashes her around quite often". :mrgreen:

Just goes to show ya can learn something new every day.

Paul, are you running scintered metallic EBC pads or regular organic OEM ones? Reason why I ask is that the EBC pads are designed to transfer heat to the calipers themselves; instead of the rotors.

The OEM's will transfer heat to the rotors and keep most of it away from the calipers.

I seen your tires dude your a better rider in the twisties then I am for sure

Will, I'm running SBS disc pads, 674LS is the number on the pack but really don't know if these hold the heat or transfer the heat to the Caliper.
If I don't have any success I'll get a set of OEM ones and see how those go.

Ian, I'm not 100% sure if the pads are retracting completely or not, perhaps I should strip and clean the caliper completely to ensure that they are.
And no, not resting my foot on the brake lever.

So I'll change the fluid first cos that's the easiest, if no luck will then strip the Caliper, May do this at the same time, will see how time goes.
Will have another think about it after I've done the above and gauged the results.

Thanks for your input Guys.

Scott, :mrgreen: but the bike just loves to blast through the hills, I'm just along for the ride.

I was out for a 300 mile ride over the weekend, up, over and around the Coromandle Peninsular (North Island)
Here's some shots of the road.

These two taken from Google maps, I was too busy riding to stop and take photos






In Thames Township.

Well if I had roads like that around here I would probably be better in the twisties. But hey I have gotten good at high speeds and landing the beast after she goes airborne above 140 I have a place I like to ride by when the road partiers are out just so they can see me clear the bridge over the river without touching any of the concrete structure

Cool :mrgreen: I would love to watch that.

And I can appreciate the skills involved in a 140MPH landing Scott:-D

Ya thats why I do not use the Triumoh fog lights any more the brackets do not hold up at high speeds. The last one I broke was on landing the beast. The funny thing is they do not break in the bend areas always on the flats.

Off subject, but hows the Battle scares etc healing from your big off ?

Not bad the wrist is still sore which will take a while to heal the back although it hurts occasionally is about as good as you can get for having six fractures in it. Good enough for me to be thinking about the Ohio Mile next May I would not recommend going thru this though. In fact I would say not recking a bike is the best thing to adhere to. The wifey does not want me to run the LSR but as long as I get a insurance policy she says she can live with it. I got to say I cannot blame her as running them races is akin to operating in the death zone !!!!

I just got this feeling that if I do not try it I will not have lived yet !!!!!!!!!!!!!
Besides what better then doing it on your own with no sponsors!!!!!!!!!

Rock on dude! I've gotten off twice in 33 years of riding and will always get back on... Bones heal, new bikes come along shortly and the spirit still soars!
