Time for new brakes



Any recommendations? Its an 02 330i with ~43,XXX miles and I'm guessing they are the original pads and rotors. I need to go pull the wheels and find out if its the fronts or rears but I want to have an idea on what I should get. Also do you guys usually replaces the pads and rotors? Any idea when the light usually comes on, i.e. do I still have some time before they need replaces?

Thanks guys

From what I remember, you have about 1,000 miles after the light comes on... but I always do it when it comes on and not push it. But, it doesn't really matter since you have to replace the pads and rotors every time anyway. I used ceramics last time, and I will not use them again... they are too soft for me, they don't fade but the OEM bite is not there.

Our stock type replacement kit (LINK) with Meyle rotors and Vaico pads has been getting good feed back from customers. It provides you with coated rotors (to protect against rusting and corrosion) and Vaico pads which are similar in characteristics to the stock pads.

If you wanted to switch to a low dust pad I'd suggest making the move to Hawk HPS, they are a performance upgrade for your car and a great all around pad. We pair them in service kits with oru ECS GEOMET slotted or drilled and slotted rotors (LINK).

If you choose to go with individual components and pick your own package basically keep in mind because the wear sensor has tripped you'll need to replace it as well. I've found MTC and Uro sensors (LINK) to be great, they are budget friendly and get the job done.

This is incorrect and potentially dangerous. You only have two sensors, not four. One on front left and one on rear right. If , for instance, you have uneven brake wear and your front right is more worn than the front left, the sensor would not let you know that. I recently changed my brakes after the front right got so thin that I had metal grinding on metal. The sensor never tripped.

Change your brakes ASAP. I got OE replacements from oembimmerparts for $110 shipped.

+1 for the OEM parts at oembimmerparts. Just be prepared for the usual large amounts of brake dust. Get Porterfield R4S pads as alternatives for OEM replacements with the stock OEM Zimmerman rotors if you want very low dust, same OEM bite but better thermal resistance, quiet and is the same price.

Btw, this topic has been discussed to death, search is your friend.

I like using an OEM rotors and Brembro brake pads. Brake dust I don't mind because I know my car is working. Plus you can always wash it off. lol

OEM rotors because it will fit best with your car.

325i needs rotors

Hi Guys,
New to the site and BMW...just picked up my first bimmer a 2003 325i about 6 months ago. the car is in great shape and I love to drive it. But I do need front rotors...got several quotes from Napa from $45 per rotor to $145... the dealer wants $100 per rotor. what's the general rule of thumb when looking for new rotors? What do I need to look for, any suggested brands that I should stick with?

ps: my pads look fine, about 1/2 of the pad is left.

thanks,
doug v

You don`t replace just the rotors, and not the pads. What makes you think you "need" rotors ? Did you measure them with a caliper ? If yes, what was the thickness ?

I brought it into a shop to try and figure out why the brakes were squeeky, but the warning light failed to go off. the response was...change the rotors.

but that's a good point, i didn't measure the rotors, but did a visual on the pads. they look pretty good to the untrained eye.

any suggestions?

thanks for the answers.
doug.

Yeah....don`t listen to the boneheads who are trying to sell you something you don`t really need.

Here`s a DIY you can try, and it`ll only cost you a couple of bucks. Get some anti-squeal compound, and apply it to the rear surface of your brake pads. That annoying high-pitched squeal is usually caused by high-frequency vibration, and the paste (compound) dampens those vibrations.

Could be the type of pad you're running... do you know the history of the brakes? You should inspect the pads and sensors just to be sure they are what we assume. Someone could bypass the sensor so it will never trip.

Another free trick... hose down the rotors and let them rust over, then go for a drive and do some hard stops - being safe to do this on a deserted road with no one behind you. If there's any gunk built up on pad or rotor, this will scrub it off nicely.

Check http://www.ecstuning.com/ and http://www.bavauto.com/ for kits that include pads, rotors and sensors. I would replace everything at once. I can't see why your rotors would go before your pads though. All 4 pads went on my car at once.
