'99 B3000 Clutch Whooo noise; Plus brake question.

[Wolfe]

After purchasing a 99 troy lee Mazda b3000 the clutch started making a whooo noise while i was releasing the clutch through the friction zone. At first I thought it was the pedal making the noise as it pivoted because it was very quiet. Now that I've moved to a more hilly area the noise has become much more profound due to the higher load I put on the clutch while trying to start from a stop. So the higher the rpms, the louder the whoooo noise. It will make the same noise through 2nd gear. Once the clutch is all the way disengaged there is no noise. Any ideas on what this could be?

My first guesses where glazed clutch, pivot bearing or throwout bearing. However I now dont think it could be the later two since the noises they make dont really match up to this one.

Now for the brake question. Recently I replaced the front and rear pads on my truck, and all was good for the first 4000 miles. Now the pedal has a little play but once the brakes engage, THEY ENGAGE! The front wheels will very easily lock up and slide. There is no abs light on and all the fuses are in place? Im going to take my wheels off and check to see if anything obvious is wrong. The fluid is full as well.

Any help with either of these would be fantastic. And its a great little community you guys have going here!

Interestingly enough I've solved the whoooo noise. I thought it was the clutch but it was actually the serpentine belt slipping on one of the pulleys. Odd huh? Well now that thats solved all Im left with is the brake problem. Any ideas on this?

There was a TSB on the clutch "hoot".
My 2000 did it and I ignored it. The boy is still driving it with no issue, still original clutch.

It sounds like your rear brakes aren't properly adjusted and the fronts are doing all the work. I've done a ton of brake jobs on all kinds of vehicles and have found grabby front brakes are nearly ALWAYS because of worn or maladjusted rear shoes.

The new play in your pedal confirms that. You might also verify that the star adjusters are on the correct side, if there is any chance they got swapped or replaced. When installed on the wrong side, they will loosen the brakes each time you back up or use the E-brake. They are usually marked L and R. I always disassemble them, clean the threads with a wire wheel and lightly grease them with disc brake grease (high temp).
