Squeal as in make a high pitch noise like screeching (or young girl screaming when she has a tantrum). Sometimes (in wet countries) the brakes can make a grinding noise when used the first few times (e.g. every morning) but that is because there is surface rust on the disks/rotors. i asked around a > little and some people suggest that i have the brake booster checked, Nahhh, have it checked last if at all. > some people say that i should have the brakes replaced, Maybe, but no., and some say > that since the noise goes away after five minutes it should not be a > problem yet.

Nothing needs to be changed yet (but you will find what is what once you take the brakes apart). If you want to cure the problem you have to remove the brake pads clean the areas they touch ... apply plenty of copper grease (a copper based paste which has a high melting point and is used to lubricate brakes). Dry brakes or accumulation of dust on the pads surfaces can produce the squealing you probably describe. All said and done it is just noise from vibrating parts, it does not change the ability of the car to stop. Read the WARNING below though :-) > > i really appreciate your help. > thanks. > WARNING! As this is your first car you should get yourself the necessary tools and you should get a manual. I use Haynes ... it might help if we know where you are located (which country). For example, if brake pads are too worn the manual will explain the minimum thickness. If you remove the rear pads you have to know how to adjust/set the hand brake (parking brake, emergency brake). Further, ask people near you who know (but from what you said above they don't know too much). 1. You need to jack the car up in order to remove the brake pads. When you do so you must support it on proper stands NOT on the jack. 2. You must NOT contaminate the surface of the pads or of the disks with copper paste, grease or any other oil. 3. And on it goes ... :-) ... Telling you what the solution is, is dangerous unless you know how to fix things ;-) Regards Charles -- Please remove _removeme_ to reply.
