Okay, I just redid my front brakes, I didnt get new bearings but I VERY thoroughly cleaned then and put all new grease, ( I know how to kneed grease into a bearing) I did everything perfect. The bearings looked good when they came out.

After driving for about a hour, with some hard braking to seat the new pads, the bearings were pretty hot, I could touch them for a few seconds but they were pretty hot. Is this normal.

plus there was a slight grinding coming from the right when I braked at low speeds. No sound higher than 30 mph.

I will be running the car up to a racetrack in about a hour. its kind of a rally up there. at least 100+ the whole way. should i worry about this.

 

i should note that I forgot to install the anti rattle spring on both sides, whould this cause the noise. Thats what Im thinking.

 

i trust you when you say you know how to "knead" the bearings, so i'll assume that everything was done right.

as far as bearings being hot, i'm surprised that you were able to touch them AT ALL, much less for a few seconds. regardless of how much grease and what-have-you is in there, they're still rotation points for a 2300+ pound car and the friction is still going to produce a lot HEAT! so yeah ... i'd say it's pretty normal.

as for the noise, i have no idea what an anti-rattle spring is, so i don't know what to say about that. if it were the bearing making noise it should be a "grinding" noise and the wheel (9 times out of 10) would look off camber. sorry i couldn't help any more ...

 

You need the anti-rattle springs - put them on. While your at it (if you haven't already), make sure you use the brake grease on the back of the pads - without it, and the springs, the vibration will cause a grind noise. I just had this very problem - the grind you hear is not your bearing but your brakes (although it sounds like bearings)
