How long do brake discs last for?

If I get my brake pads changed before they wear to the brake disc, will I be ok to continue using the same brake discs?



If I removed a wheel... how exactly would I tell if a brake disc is worn? Looks like a big circular dish of silver to me.



(Mine are disc brakes not drum brakes).

You'll be fine using existing discs providing they are in a servicable condition, you would be better to have a qualified mechanic take a look, brakes are so important....

disc's can last at least three sets of pads before they need changing. i work in garage in spain over here they dont change discs until they can slice meat, it's not the best thing to do!!How long do brake discs last for?
If you change your pads before they wear down yes this will stop them damaging the disc.

If you take the wheel off your car and run your finger from the inside of the disc to the outside of the disc and feel no rdieg at the outer edge then your disc is ok. If there is a ridge at the outer edge of the disc you want to query this. If you are not that familiar yourself with brake systems most garages do a free brake inspection, they will be able to tell you if you require new discs.

A disc can also be warped, you would usually notice this by a chuffing noise when driving along, braking or a slight wabble on your steering under braking.

i change my pads every 3000 miles. but you dont have to. when the pads start squeeking it means that tey are worn. if you see grooves on the discs that means that the worn pads is digging into them.How long do brake discs last for?
it all depends on how you use them really. Some people ride the brakes allot and others don't do that at all. You will be able to tell when you need new brakes and if you do need new ones you have to do both sides. There is no getting around just doing one side but you can do the front say one week and the next week doing the rear. That is if you cant pay for all four at the same time. You can call around and see who in your area can look at your brakes for fee and your router as well to see how they are and you can do this as often as you like the service is free. So have them checked ever so often its safer then just waiting tell the pads are gone and you also need to replace your router at the same time and trust me having a place do it is allot of money later. So take care of the brakes by having them checked out for free at a place near you.How long do brake discs last for?
Hi no you dont always have to change your disc's run your finger on the face of the disc starting near the middle and working to the edge if there is a bump then your discs are worn and will need either re- facing (grinding the disc flat) or replaceing, if the disc has a blue tint to it it means there has been to much heat on the disc and it needs changingHow long do brake discs last for?
Preventitive maintenace is key to avoiding break failure. If you own a car, sometimes there is a painted area of your pads that indicate you need to replace the pads or a metal prong that will make your breaks noisy when its time to replace them too. If you own a motorcycle, there is a ridge that will become thinner. You may get 75,000 miles from your discs if you change you pads often and do alot of freeway miles.

The life of the brake parts can depend on your driving style, if you are hard and late braker for example you can expect the pads to have a shorter life than if you are a smooth progressive braker.



Your discs and pads can last for years and I'm talking ten years or more, I got that out of my last car. Pads are more likely to wear out than discs. It is ok to change the pads and continue with the same discs.



Modern cars will have some sort of warning that the pads are wearing either an electronic light or just a spring arrangement that rubs on the discs and makes a noise to alert you when wear is setting in.How long do brake discs last for?
Wear on brakes varies according to the type of car and the type of driving involved. You should always change the pads before they reach the point where the metal section touches the disc. On most modern cars there is some sort of indicator, a simple one being a small metal piece which makes a noise to warn that the pads need changing. The discs usually wear at a much slower rate but need to be inspected for score lines/ridges on the shiny part of the disc. Also the part of the disc where the pads make contact will wear and this will show because it creates quite a ridge on both sides if it. Brakes are not for the unsure mechanic and I advise that you have them inspected at a local garage. If you ask them, most small garages will allow you to watch as your car is inspected.How long do brake discs last for?
when you have your brakes serviced, always have your rotors (disc) resurfaced to ensure a nice, flat surface for your new pads... a typical rotor can be resurfaced up to 3 times depending on how much it has been resurfaced... a shop will measure the rotor thickness and make sure it is safe enough to resurface, if it is not, replacement is necessary... easy way to tell if you need new rotors is to feel for deep grooves in the rotor or on the end of the rotor, if you feel a lip on the end, it is replacement timeHow long do brake discs last for?
generally the brake discs or rotors are good for two sets of brake pads. if you have any surging when you are applying your brakes the brake rotors are warped and should be replaced. also if you have any grooves or chips out of your rotors they need replaced. it is possible to resurface the rotors but the cost of new rotors has gone down so much you are better off just buying a new set if yours are worn badly. dont skimp on the brake pads the cheaper ones tend to be more metallic and can be noisy.How long do brake discs last for?
There is always a minimum disc thickness quoted ...look in hand book or ask local garage man...
