One can purchase brake discs from a variety of stores. Stores such as AutoAnything, eBay, GSF Car Parts, Auto Parts Warehouse, and Walmart sell brake discs.
The best quote I've had to change pads and discs on a vauxhall omega is £182.
Depends on what kind of "discs" you're referring to... (compact discs? brake discs?)
Whenever you want to but once your brakes start squeaking that means your brake pads are low or your discs/drums are wrapped and need to be skimmed or replacing
Usually no. Shoes and discs are parts that wear out, which the caliper isn't expected to do.
Brake lights on can mean no brake fluid, worn out brake pads, faults in the master cylinder. Must take your car to the garage immediately. Worn out brake pads can damage the discs which are expensive to change.
If you change pads regularly and drive carefully they should last the life of the car, at least 150-200, 000 miles. -I have only ever had to change discs when people before me have abused the brakes.
there are brake shoes in the discs too . just remove the discs and you will see them. they are applied by a cable.
NO! No...no...no...! Do not put any grease on your brake discs, copper grease is used to put on the 'back' of the brake pads (not the part of the pad that comes into contact with the disc).
Changing brake discs and pads is very easy and will take less than an hour on most vehicles. Modern pads and discs are much the same to replace on most cars. Car Parts Direct have a five minute video to show you how to replace your brakes. They also have discounted brakes you can buy online.
Typically integral parking brakes are on rear disc braking systems. By activating the parking brake it adjusts the discs on the rear brakes. While the front discs are self adjusting, on the integral systems the rear discs are not self adjusting, thus the need for the integral parking brake system.
