Pulsing in Pedals

Hi All,
Not sure where this one goes, so I picked suspension/drivetrain.

This morning I woke up and found that I had a flat tire on the rear driver side. The tires were getting old, so maybe it was a sign to get new tires, which I did. On the way over to the tire shop, riding on the donut, I felt a pulsing/rattle from the brake&clutch pedals as I slowed down (it only got noticeable are 15 mph). I figured it had something to do with the donut. Sadly, even with the new tires, I get the same pulse - it's never at high speeds though. They checked the alignment at the shop when they put on the new tires - everything checked out. I adjusted the clutch, which took care of the rattling sound from that pedal - but the brake still is strange.

Not sure where to go on this one - new front rotors/pads about 4000 miles ago. Rear brakes are still visibly ok (but I'm not a brake specialist).

Any thoughts? Sorry for the long post.

It sounds almost like there may be air in the brake lines??? Do you know if the brakes where bleed after replacing them?

the brakes could need bleeding, but you surly would have noticed this before 4k miles, its worth a shot though.

If your rotors were messed up you would feel it when braking but the steering wheel would probably shake also.

or you got a troll in your car and he/she (but really girl trolls dont get in cars they are more like moped and bird nest type trolls) likes to mess with your brake petal, its a 50/50 chance thing, either what i said or corey just check for both. OH, If you do find a troll dont let him bit you, cuz it will hurt.

Apparently, it was the troll. I was driving to work today and it seems like the car healed itself. Nice! The troll was just waiting for the rain to pass over I guess.

The rattle is back. I took it to the dealer to see if it was either the TOB or the clutch itself - neither was the case (AND they didn't charge me for looking at it). Good news that I don't need a new clutch, bad news that they didn't see what was wrong.
I find that after shifting, lifting up lightly on the clutch pedal eliminates the rattle too (along with holding it down lightly). I think that the quadrant may not be right, so I got a new UPR clutch cable/quadrant/adjustment nut. If it turns out not to be the problem, at least I have a new UPR clutch cable/quadrant/adjustment nut.
Is there a nice step-by-step installation out there for replacing the stock stuff with adjustable aftermarket (I'm thinking that the instructions would be the same for UPR/Steeda/whoever else). Help is always appreciated! Thanks!

the installation is very straight forward, if the upr looks just like the steeda then i would say to use the same instructions.

if lifting up on the clutch petal or putting a little pressure on the clutch petal makes the noise go away then it IS the throw out bearing, if you act fast enough and get a quadrent and firewall adjuster you can take the slack out of it and perhaps save you the price of a new throw out bearing..... thats the problem for sure though.

Just as closure - the quadrant/cable/firewall adjuster solved the problem - no more pulsing, no more noises.
