Front brake clicking noise

When I use the front brake above about 20 mph it makes a rhythmic clicking sound until I get down to about 20 mph. I've looked at the rotors and don't see anything that looks like it could catch the caliper as it goes around. I don't think its suspension related because the noise continues.

Try running you finger tips lightly over the whole surface of the rotors, as you would when feather sanding a panel prior to painting. Your sense of touch will often detect an imperfection you can`t see. Just an idea, but try lightly "sanding" or buffing each side of both rotors in a circular pattern, with a piece of fine emery cloth or coarse wet and dry sandpaper.

Let us know what you find, or if the buffing helps.

My 95 did the same thing. Flushing the brake fluid w/new fixed the problem. Now my brakes are smooth and quiet.

Sorry, I would not suggest sanding the rotors. If they seem off , take them to a shop and have them machined or replace them...but I doubt that the rotor is making the noise...it is more than likely one of the pads.

You should check the wear indicators to see if they are worn. It might just be one pad... If they all look good do as dirtrack said and try flushing the old fluid and replacing it with new. After bleeding see if you still hear the noise.

It might be something else on the wheel making the noise...like a bad bearing.

The Clymer manual says the rotors are not thick enough to machine down. My *sanding* or buffing suggestion is along the lines of smoothing a minor roughness or surface rust, or buffing off a gasket surface, not taking it down a thousandth or two.

The OP says it is a *rhythmic clicking* which sounds rotational to me, not constant as a faulty pad would likely be. That said, my experience is with automotive brakes not motorcycles, so any of the previous mentioned causes are possible and should be investigated.

Two other ideas,

1. I always *break* or chamfer the leading edge of the new brake pads at 45* with a grinder or file before installing them to avoid squealing noises.

2. Possible speedo gear drive noise?

And I would trust you to sand your rotors OlHoss...but as I am not privy to the amount of technical or mechinical knowledge the OP has, I would be very hesitant in suggesting they grab some sandpaper and go at it. It is very hard to sand something like a rotor evenly, unless you take them off the wheel and use a sanding block.

You also need to be very sure you clean off any traces of sanding abrasives , and not use too course of paper.........

Given that the OP may not be very mechinically inclined, I wrote my post with that in mind.



Light rust should come off with use really, so checking the pads and the caliphiers seems more worthwhile....

I do agree with chamfering the pads edges and ... that the noise may not be from the brakes themselves.


Always hard diagnosing something with only a somewhat vague discription....

Mine would click once in awhile going forward after backing up, then braking. I would just use them as normal, and it would go away.
