This question is aimed primarily at pimpscort cause he´s a mechanic. When I´m coming to a stop and get to a real low speed, like 10 mph I hear a click click sound from my right front brake...I dunno what it is and the brake grabs just fine even while doing it. I can almost feel it in the pedal and Brian can hear it easily. I haven´t had a chance to get under there to see what it is.

I do have a piece of the splash guard hanging there when the screw popped out whilest i was taking off the broken and tie wrapped pieces of the underbody plastic.

Any Ideas? :-?

First of thanks for the Props James. I´m glad someone recognizes my skills and extensive training.

Next could you go into a little more detail about this clicking sound??? Does it get slower as you slow down? Does it go away if you let off of the brakes and just roll? Does it only happen when you brake, or does it click when you first start to roll away from a stop. Does it do it only with the clutch in or does it only do it with the clutch out and the tranny out of gear. Can you see any debris around the caliper, i.e. a stick, piece of plastic, anything that looks like it shouldnt be there... The fact that you hav a spash guard hanging down in that area concerns me. I did some work on a 91 Plymouth Acclaim where they would get a whining sound from the front right tire when the would go over 45 or so, that turned out to be a piece of the plastic from under the fender that had come loose and would bend enough due to wind resistance when it got up to speed then it would rub the tire. Maybe you have something on the backside that is doing the opposite. Maybe the wind will hold it back, and it will come into play when you slow down. Or maybe it is clicking all the time and you can only hear it when you are going slow. Give me some more info and I will help as much as I can

~No Problem. You´re my idol. Being a mechanic and all. (seriously, there´s no sarcasm there at all.)

Next could you go into a little more detail about this clicking sound???
~Sure.

Does it get slower as you slow down?
~Yes

Does it go away if you let off of the brakes and just roll?
~Yes it goes away.

Does it only happen when you brake, or does it click when you first start to roll away from a stop.
~Just when I brake, and only at about 10 mph or so. if I´m power braking and the car dives forward it doesn´t happen, or at least I can´t feel/hear it.

Does it do it only with the clutch in or does it only do it with the clutch out and the tranny out of gear.
~It´ll do it with the clutch out, and it´ll do it with the clutch in as well. Also, I normally don´t pull it out of gear until I come to a complete stop. unless I´m expecting the light to change and I want to power out of the intersection.

Can you see any debris around the caliper, i.e. a stick, piece of plastic, anything that looks like it shouldnt be there...
~Haven´t had time to look to tell you the truth. I haven´t spotted anything out of the ordinary, and i´m not suspicious of debris because that tire is always on the side of the driveway where there isn´t anything. (I have trees in my yard but my neighbor doesn´t.)

The fact that you hav a spash guard hanging down in that area concerns me.
~It´ll ONLY reach the tire when I´ve locked the wheel to the left as far as I can tell....it sounds horrible, and on the highway i´ve never felt/heard it hit the tire.

Thanks in advance.

sorry to be off topic, but what is power braking? and how do people do burnouts? I don´t see how they lock up just the front wheels so they can spin the rear wheels... I´m not sure how that works...

and to a n00b like me, it sounds like you may want to check your tierod ends, bearings, pads, and discs.

do you feel any shaking under hard braking? Any pull to one side?
sorry I´m not better at this, but I´ll try to help with my limited knowledge.

oh yeah!!
wait!
my cousin in massachusettes had this same kinda problem last week. It turned out to be a loose bolt on his wheels. As in, one of the lug nuts was loose on his wheel.

Also check the balancing weights on the wheels... maybe that´s it.

and yeah kudos to pimpscort89... he´s really saved my ass many times over. if I werent so poor paying for my own tuition I´d help a brotha out.

what i meant by power braking is when you realize you need to stop before it´s too late and you cram the brakes as far as you can without locking the wheels up.

My tierods are old and my alignment is way off. that could be part of it.

Normally power braking is where you use your left foot in an automatic equipped RWD car to hold the brakes just enough to keep the car still while flooring the accelerator with your right foot and melting the tires. Since up to 80% of your braking force is in the front, the engine can often turn (overpower) the rear brakes despite the fronts being locked solid.

James, braking to where the tires are just about to lockup is often referred to in the mags as ´threshold braking´... it´s what ABS brakes attempt to emulate.

Pimp is the man, there are lots of mechanics out there, but few are willing to help out the fledglings like us, while studying the mechanical theory. :-]

James, you are indeed correct that it could be your tie rod ends. If they are worn out and have some play, at low speeds under braking, they could be alowing the wheel to shudder if the alignment is bad, causing the noise and vibration. I would hope your lug nuts are tight, as they too will cause this noise and feeling. a slightly warped rotor may also be the cause.

Thank you and your welcome to Siragain and Beaverboy as well. I guess it´s the thought that counts, right Sir?

Ok my thoughts are leaning toward a bad CV joint. The reason I am leaning toward this and not the tie rods is that the outer joint of a CV joint has ball bearing that ride on a star shaped race and they are held in place by a metal cage that the joint fits around. If one or more of theses balls are damaged or if there is no grease around them, they may be shaking around in the cage. At higher speeds it may be held to the cage by centrifugal force and maybe the load of the star shaped raceholding it onto the cage, but one you brake and the load is released the ball can flop around once centrifugal force can no longer support it. Then whe you drive away again the load on the joint will grab the ball again therefore not being able to hear the clicking when you are accelerating. The warped rotor pulsating pedal feeling may be from the ball being smashed around in the cage. Take a look at your CV boot to see if it is torn, and see if there is any grease thrown around on the underside of your car. If not, then it may have failed due the greas inside the joint being contaminated from a previous boot replacement, or not enough grease was but in there after a previous repair.

Hopefully that helped you out. Make sure you check everyting out. You might try jacking up the front side of the car putting the tranny in neutral, and turning the wheel back and forth to see if you can hear the clicking. Make sure you block the back wheels when you jack it up.

As far as the power brakeing goes, Beav is right about the holding the brakes and roasting the tires on an RWD car. To further answer Sir´s question about locking up one set of brakes and roasting the opposite set of tire, racers will often use what is called Roll Control, or Line-Lock. What this is, is a solenoid that is plumbed into one circuit of the braking system, Front for RWD cars and back for FWD cars. The driver will get his driving tires in the water box, and pus the brakepedal to the floor. After doing that he will push a button to activate the solenoid. This will lock all the brake fluid to the specific circuit in place. now the driver can release the pedal and floor it while the brakes are being held on the non driving wheels. After the burnout he will release the button and the remaining brakes will be released. This also come in handy on Automatic tranny cars when they are staged at the tree. The lock can be set and the revs brought up to launch rpm and the the button can be released as the gas pedal is floored and the car will launch intantly. (not only am I a Mechanic, I am a drag racer ;-), well was until I get my Mustang running again)

It´s helping me, how much I don´t know yet. I would like to know what the problem is so I can get it fixed asap. I´m not a suspsension guru and have never even played with the suspension. So thanks for the help. ;-)

Well, I have KYB Struts, Suspension tech lowering springs, Power slot cross drilled and slotted rotors, and EBC green stuff pads. All I need to do is get a hold of the tie rods, install it all, take it to a shop and have them align it and I should be set right? They wanted 800 bucks to install all that and I said screw that shit. I´ll install it myself or with some help and you guys can align it. but you´re not getting 800 bucks out of me to put on shit I already have.

and after all of that is installed you will still have a clicking noise if your CV joint is bad. As far as alignments go I did a search on how to do an alignment at home almost a year ago I think, and it doesn´t seem like it would be that hard to do. Granted the machines are easier by far but it is possible to DIY.

Ok i´m missing what the CV joint is/does. Is there a way to explain where it is and what it is attached to? I know where the driveshaft goes into the transmission, as I about welded my wratchet to Brians when I was taking his starter off...(remember to unplug the battery hehe). but thats about all I know about it. I didn´t look at it all that much.

Ah, sorry for that, I thought everyone new what a CV joint is. My bad. So anyway a Constant Velocity joint aka CV joint is the joint at either end of what you refered to as the drive shaft. It has the dunce cap looking acordian like boot on each end that covers the CV joint. Each boot and joint is filled with grease to keep the joints lubed. The pupose of the joint is to allow the wheel to be able to turn and take bumps while keepin the wheels at a constant velocity since just a strait axle wouldn´t be able to do that. What you refere to as the drive shaft is reall an Axle, or sometimes called a half shaft, or CV Shaft.

yeah i´m not mechanically inclinded by the way of suspension set up. You´d be just as confused if I were to start babbling on about Phone systems like the WIN, Comdial, Nitsuko, etc. I´m still confused myself about it all.

I know what you´re talking about now though. Thanks

first off all I did was skim across the contents of this post so if this was mentioned already just disregard. I have been haveing a clicking noise from my right front but I know part of the problem already....when I changed my front wheel bearings awhile back before I went to Germany, while getting the races removed from the spindles I let a guy at the shop take them off with a cutting torch...the left side went along fin...but the right side got a small nick in it...but being on a tight time schedule and already low on funds I put in the new bearing and went on my way...it was all fine until I got back from Germany and took her out of storage, I started noicing it when I would come almost to a complete stop....it´s been getting worse for awhile now...but I got the parts to cure it today and will be installing them this weekend. I don´t know if that will help any at all, but it´s my two cents worth

well what I went with was replacing the whole hub and spindle assembly...I have a guy not far from here that wrecks out almost nothing bu Escorts....he gave me the one I have but then again I had just bought a motor from him....if you would like I can see if he has another low mileage one he can get off a car and how much he´d charge for it

OK there´s another cause of clicking in the front end which will start as a clicking but grow into wobble and you should check for this when ya jack it up and roll that rim.A bent half shaft seems to bind the cv joints as it rolls around. I have never figured this one out but I have seen a few scorts with the right half shaft bent.I don´t think they would make enough torque, but I have never seen evidence of outside forces.Oh well just a thought.Loose brake hardware could do it too.
