Big problem- disc brakes

I just bought an 08 gary fisher marlin about a month ago. I've been having problems with the disc brakes ever since. For the first few days, the brakes would squeek constantly and really had to squeeze hard to stop. I kind of expected this until they broke in. The squeeking continued and someone sprayed my triflow on both brakes without my knowledge, figuring that would help. I cleaned the outer part with alcohol wipes, but I'm wondering what else is going to happen to the breaks. I don't know the mechanics very well, but any suggestions would help. I should add that the bike is still under warranty. Thanks

You'll need to replace the pads and clean the rotors. The pads won't be covered under any warranty.

Whoever sprayed lube on the brakes is Not a mechanic. Brakes require friction to function properly... Now what is the purpose of lube? Anyone? Ah, that's right, to reduce friction. I agree with Zumba, although purchase 10 ft. of rope to be on the safe side.

Perhaps speak with the shop owner to see if he knows of his employees unsafe practices. You may be able to get a set of pads out of the deal if you're lucky.

if the triflow hasn't penetrated to far into the pads you can sand off the outher layer with fine grit sandpaper, but they are prolly toast, and sanding isn't a guaranteed fix, but in the future if you pick up a little contamination and hear squeeking, you can just sand the pads, full on grease spary however...

I'm probably going to go to my shop tomorrow or so and have them put new pads on. Is there anything else that would have been damaged, other than the pads? I already rubbed the rotors with alcohol- who knows maybe this whole thing was causing the insane squeeking too. As far as the warranty goes, it wasn't one of the mechanics who did it, someone around my house. Shouldn't run too much though, 20 bucks maybe?

20bucks for 1 brake i think, so if both brakes got sprayed...

i don't think pad replacement on discs is somthing that warrents having a tech do it, mostly b/c you should learn how do adjust your brakes, incase somthin happens on the trail or w/e

You see this "friend of mine". . . Was this in a dream? What did Freud say?

Just to throw this in there, my brand new Trek with deore hydraulics has not needed a break-in period. It has not squeaked yet, and stops plenty fast. So I would change the pads and be done with it.

Squeaking and creaking and popping are not typically good things with a MTB. Quoting from another source: "Often the sign of something that is going to wear out, fail or leave you chewing dirt." i.e. creaks and stuff means they want to be tightened or adjusted.

Another possibility (which I doubt is the problem since there was Triflo put on your brakes) would be too much slack in your brake cables (or lack of hydraulic fluid if you have that style).

Haha, it actually was someone in my family- believe me or not, dont' really care. They took it out for a ride and notice the squeek, etc. Anyways, should have the problem solved in a day or two. Thanks for the input, just joined the forum and have already loved searching through it.
