Question about 2003 BMW 325

3 Answers

325 ci brake rotors have been replaced 4 times in 6 years

My question is the following: Do 325 ci brake rotors need to be replaced, or can I just replace the brake pads? My service tech at BMW has advised me to replace the rear rotors twice (at 30,000 miles each time) and front rotors twice (at 30,000 miles each time). Why can't I just replace the pads as long as there is no wear on the rotors?
Thank you,
Leila Faber

    Thank you for your response. Yes, I did ask if I could just replace the pads before they were worn down to the rotors. They said the only way to keep track of that is to come in every 2 months to have the pad thickness measured. ???

BMW rotors are not known for lasting very much more than 30-45k miles. When the brakes are inspected, they measure the pads using a special tool threw the outer brake pad. Min spec is 3mm. When the pads are replaced, they measure the thickness of the rotors. The rotor spec is stamped on the rotor. if they are under that spec, they recommend replacing them as well. Next time you bring it in for service, just ask them to measure the rotor thinkness, (its not a huge task, all they have to do is take the wheels off). But more often than not, the rotors wear just as fast as the pads.

Djmac62,

Not true as far as BMW starting from some yar back. I happen to replace brakes on my cars and yes aI can do pads. BMW however requires front trotors replaced with every change of pads. This is BMW (manufacturer) recomendations and not a repair shop. This is new Euro norm and rotors are now made softer so match between pads and rotors are better and braking power is higher.

With older models you could replace only pads and perhaps just resurface old rotors.

How to replace rear brake rotors on 06 commander?


I Just replaced my rotors on a commander that I've owned for for 6 years. once you get the tire and brake caliper assembly off. You will need to make sure the the Parking/emergence brake is not engaged, if it is the drum brakes under the rotor will give you a very hard time. Finally if you know you are getting rid of the rotor take a good heavy hammer or mallet and wack away at the disc portion of the rotor. i would go around the rotor top to bottom, side to side till it comes loose. don't be afraid to hit it hard. I would recommend eye protection.

2005 Pontiac Montana brakes wear out 3-4 times a year have replaced calibers and rotors still wearing out. please help


You know this is hard to believe. Brake pads should go at least 40,000 even on the front. Calipers should last about 10 to 12 years. That's my record for 46 years running.I wish I had the vehicle and time to review this with you. Start from 05 and discribe every brake issues and EXACTLY what was done and why/

Brakes pads and rotors


Yes, he is trying to make money. Tell him to turn the rotors if they are within tolerance and call it a day. The service writer who told you that gets paid on all the parts you replace when in for service. BMW rotors are a pretty soft metal and that is what makes BMW the best stopping car in the world. They turn rotors daily in that shop so don't let them kid you. You should be able to turn the rotors a couple of times before they require replacement, which should be around 75k miles. If you run it hard though it will be under 50k miles. Please email me with any questions and please leave me a good rating. ceo@teampar.com

LOW BRAKE PEDAL ON 4 WHEEL DISK BRAKES


Check the pads/rotors to see if they need to be replaced.
Check the brake fluid level. If low it could mean the pads/rotors need to be replaced. If replacing also replace the brake fluid.
Two years probably means you need a brake job.

Otherwise you may have air in the brake lines which you can bleed off.

My 2004 BMW 325 ci convertible is difficult to start.


If the fuel filter has been replaced, then maybe these are other reasons:

1. intake camshaft sensor (known to go bad on BMW E46s). ~$100 part.

2. fuel injectors (though I doubt they go bad that easily). ~$100/ piece. Your car has 6.

3. Ignition coils. ~$90 a piece. Your car has 6.

4. mass air flow sensor. Again, another expensive part. ~$300.

BRAKE WARNING LIGHT


I dunno if this will work on your BMW, but on my BMW Z3 and M3, it was....

Turn the ignition key to position 2, but do NOT start the car. Wait for about 45 seconds and the brake warning message will be reset.

If it doesn't reset, then the brake sensor was damage. You will need to replace the brake sensor. It sounds like you replace the brake right after you saw the warning, so the brake sensor should be okay.

Reconnecting caliper to rotor on 2005 pt cruiser


you need to open the caliper bleader valve and release the preasure out of the line. so that the brakes will retrat against the caliber. than you should be able to put them on the rotor. they might be a little snug but they will go on. than close the caliber. now you need to blead the brakes.
1a.Make sure that there is brake fluid in the resivoir.
1b.start the car and have it running until all the brakes have been blead up.
2.Go to the passengers rear and lossen the bleader valve.
3.have someone press the break until you see a steady flow of break fluid comeing out of the line.
4.once that has happend have them press the brake again and hold it to the floor.
5. tighten the bleader valve.
6.go to the drivers rear and follow steps 1-5 again
7.go to the passangers front follow steps 1-5 again
8. go to the driver side front and follow 1-5 again.
you might have to turn the wheel so the person can reach the bleader vavle up front.
Remember to check you fluid after every time you finish with a brake so you do not runn out of fluid and put more air into the lines..... also remeber to alway start with the brake farthest away from the resivoir. you always do them in order 1passanger rear2.drivers rear 3.passangers front. 4. drivers front.
if you need further assistance please let me know
