Adjusting the rear brakes
Posted June 19, 2005 - 01:02 PM
1. Should there be this slack between the pad and the rotor?
2. How do I tighten this slack and properly adjust the brakes?

Is your caliper properly mounted?
Did anything weird happen during your wheel removal/refit?
Is the brake lever hard/have no movement?
Sorry, dumb question - is there any fluid in there?

Nothing weird happened when I took it off or put it on. As far as the flud...I "assumed" since I didn't have one drop leak it would be fine as it was before.

First off, double check the mechanical installation of the wheel, if your not sure get a second oppion.Then try cleaning the disk with a brake/clutch cleaning spray.
Once you have oil on the disk ,it get's on the pad's and the
foot peddle feels ok , but the brake only works 15% efficient.
Hope this helps

How many times have you pushed the lever through its stroke since the wheel went back on; if its only once or twice then keep on doing it, as its likely the pads were pushed back during wheel jiggling to get it out/back in.
Or, freak occurance and brake needs bleeding
That thing in the reservoir is part of the cap assembly and is supposed to be there.
Judging by the colour of the fluid I can see, it wouldn't hurt to change the fluid anyways.

I took the bike for one test ride down the runway (it's an asphault taxiway for airplanes) and then came home. I started it yesterday but only drove around the house twice.
I just took the lid off and didn't realize the black insert went down so far. The fluid is red and looks to be in pretty good shape. I didn't really have anything to clean off the rotor so I just used some carb cleaner and gave the rotor a quick spray around it. It's working a tad bit better. Unfortunately the neighbors kid is napping so I can't fire it up and try it out yet, I have a Big Gun on it and all the neighbors know it!!!

Let's hope it's just muck and reseating of pads
I have a race ackro system on my 450 and yeah, the neighbours love me too!!

Deglaze them while you're there, doesn't take two minutes. A sheet of medium sandpaper flat on a worktop and rub each pad on it until the 'shine' is gone from the surface. Don't go mad! only takes a few reps.

Most of us keep the back brake covered all the time, but rarely use it.
Just sometime's it's the only thing that can put balance & control into a given situation.
When i clean my Chane (wash my bike ) , if i get contamination on the rear brake disk, it can take several day's before the brake gets back to normal.

Or if i have given the Chane a really good de-grease & clean, the rear rotor can get covered in all sorts of crud. Often the inside of the disk ,facing the hub , where we can't see and dont clean too often.
Contamination is a general term, if the brake system is not 100% clean & dry it will
be suffering from contamination of some sorts.

PS. Sorry about the Grand Prix , what a load of cr*p.
The french ( team renault ) must be keeping a low profile now.
You yanks were rightly pissed off.
