Hello, thanks for writing in about your 2003 Hyundai Elantra. The price sounds correct for the work you said was done. You are looking at about two hours labor plus parts, shop supplies, and taxes.

How to tell whether your brakes are drum or disc. To double-check, look through one of the holes in the top of your front wheel. If you see a shiny smooth metal surface, that is your disc rotor. However, if you see a rusty and not smooth round surface, that`s your brake drum.
Auto manufacturers continue to use rear drum brakes for two main reasons – lower cost and less complexity. Drum brakes are less expensive to produce because they require fewer parts than disc brakes. Unlike disc brakes, drum brakes can function as both a service brake and a parking brake.
From the 1960s to the 1980s, disc brakes gradually replaced drum brakes on the front wheels of cars (which receive the majority of braking force). Now practically all cars use disc brakes on the front wheels, and many use disc brakes on all four wheels.
A drum brake is a brake that uses friction caused by a set of shoes or pads that press outward against a rotating cylinder-shaped part called a brake drum. The term drum brake usually means a braking system in which shoes press on the inner surface of the drum.
Every car comes with two front brakes and two rear brakes. Older vehicles typically have drum brakes in both the front and rear. In contrast, modern cars tend to have either disc brakes on all four wheels or disc brakes in the front and drum brakes in the back.
All you need is a disc brake conversion kit. Installing one of these kits is a straightforward process that involves removing the old drums, attaching a set of brackets to your wheel hub or axle flange, and then installing the rotors and calipers and hooking everything up.
Drum brake advantages
Drum brakes last longer because drum brakes have increased friction contact area than a disc. Drum brakes are cheaper to manufacture than disc brakes. Rear drum brakes generate lower heat.
Disc brakes are the more effective and reliable choice, but they have their limitations. Drum brakes are not very practical, but they are crucial to parking a car – unless of course you`d like to go back to wooden blocks on sticks. Therefore, drum brakes are often still found in modern cars.
There are three types of drum brakes depending on how the brake shoes are pressed on to the drums; leading/trailing shoe type, twin leading shoe type and duo-servo type.
Because of their superior heat capacity, discs are arguably safer than drums. But most of the braking power comes from your front brakes. Even in panic stops, your rear brakes get less stress and less heat than your front brakes.
Disc and drum brakes are based on a hydraulic pressure system. Braking starts with a mechanical force — your foot pressing the brake pedal. The end result is that your vehicle safely stops.
Rear Brakes are typically drum brakes. This type of brakes has more parts than disc brakes and is harder to service, but they are less expensive to manufacture, and they easily incorporate an emergency brake mechanism.
Why did the rear brakes wear out first, and why would one pad wear down to metal? Answer: The brakes should be checked each time the tires are rotated or twice a year. The rear brakes are much smaller than the front and will sometimes wear down before the fronts in some vehicles under certain driving conditions.
The short answer is about $600-$2,000. The long answer is that the cost of a disc brake conversion kit depends on a few factors: The number of wheels (two or four wheels) The type of rotors included in the kit.
As long as the drums will still be in spec by the time it will need relined, then yes reuse them. In other words, if the drums are more than half worn after one set of lining, REPLACE.
Drum brakes use wheel cylinders, instead of calipers. The wheel cylinder also use hydraulically applied pistons that push a pair of brake shoes against the inside of a drum in order to create the friction needed to stop.
The bearings are located in the wheel hub on disc-brake wheels, and inside the brake drum, which forms part of the hub, on drum-brake wheels. Non-driven wheel bearings – the front-wheel bearings of rear-wheel-drive cars and rear-wheel bearings of front-wheel-drive cars – are similar in design, differing only in detail.
Eventually, they wear out and require maintenance. Wheel cylinders also wear out and start to leak. Either one of these issues can cause the following problems: The back of the car shakes or pulls to one side when applying the brakes.
The average brake drum replacement cost averages between $275 and $399 depending on the type of the vehicle you have the type of repair shop you`re taking your vehicle to.
While drum brakes do have a completely different layout and mode of operation than disc brakes do, they are usually no more difficult to service, and often require only a basic set of hand tools and a drum brake adjustment tool to get the job done.
Drum brakes are very different from disc brakes, but when it comes to maintenance and repair, most drivers don`t need to worry: drum brakes can last 200,000 miles or more.
Drum brakes are supposed to last the life of your car (or about 100,000 miles), but sometimes they fail sooner than expected.
Hence, its 1st, 2nd and 3rd forms are brake, braked and braked.
Never lubricate the inside of the drum where the shoes contact the drum. Lubricating these areas can prevent the brakes from working. Use lube anywhere you find metal-to-metal contact between moving parts, such as where the shoes slide.
