LSX Performance

Hey guys. I rencetly bought a 2002 Pontiac Firebird Formula with 32K miles on it.

Ive noticed that when coming to a stop at low low speed I can feel the brakes pulsating. There is no vibration at all. Again its only at low speed when my stop is almost complete.

Most likely warped rotors, pretty common with our cars.

LSX Performance

I kinda had a feeling. With 32K miles there probably the originals.

If you want just a stock type rotor go with the Autozone Duralast rotors. They are really good against warping.

Any thoughts on the Brembo Rotors sold by tire rack? not the slotted or drilled ones just the plain ones.

Brembo blanks are the best solid style rotor, but they are kind of pricey. The Duralast ones are excellent and they only cost like $30 front and $26 rear, you cant beat that price.

Rotors for sure, last year I replaced mine and had only like 21k miles on it, the stock rotors are crap, get a set of drilled and slotted ones,it'll be better

I'd like to but im moving into a new house pretty soon and money is kinda tight.

I think i'll order the blank Brembos.

I would consider turning the brake rotors. Also check your wheel speed sensors. And check your bearings.

Pulsating brakes isn't always contributed to worn rotors.

Had the car checked by the dealer last week.

Yep its warped front rotors. Brembos rotors to the rescue

Duralast rotors turn bright red from rust within a matter of weeks. Its horrbile.

...so don't most rotors, including brembo blanks. Won't hurt you a bit, unless it bothers your eyes.

And typically the pulsating coming from "what people consider to be warped rotors" occurs when braking at highway speeds. I usually never got the pulsating at lower speeds.

I have the pulsing at low speeds and my steering wheel shakes at highway speeds when braking. I know these are symptoms of warped front rotors, but I just replaced them last summer with the Duralast ones from Autozone...and I'm not hard on the brakes. Is there an underlying problem that causes warped rotors on a yearly basis?

LSX Performance

seems to be a coming issue with these cars. from what ive read the blank brembos hold up the best as compared to other blank rotors. i got mine from tirerack. its was about $280 for all 4.

I had this same issue, put on brand new brake pads and replaced the rotors with new ones too....still have the issue. This is on a 2000 Camaro.

Before you go and dump money into your brakes. 1. I would lift the car and rock the tire at 3 and 9 next 12 and 6. This will check your ball joints, wheel bearings, and steering componants. Wheel bearings have been known to go bad often on our cars. 2. Next I would get a dial indicator and check rotor run out. It should be under .005" but I feel more comfortable around .001-.002 If you dont have a dial indicator ($20 at harborfreight sometimes with the snake) take it to a autobparts store that machines and have them measure your brake rotors for you.
