Thus, How do I know if I need new brake drums? Here are a few of the things that you may notice when it is time to replace your brake drums.
- The back of car is shaking when trying to brake.

Additionally How many miles do drum brakes last? Drum brakes are generally expected to last between 150,000 to 200,000 miles with proper care and maintenance. Their brake shoes generally need to be replaced about every 30,000 to 40,000 miles. Of course, the conditions your vehicle is exposed to over time will have an impact on drum brakes’ wear, too.
What does a broken brake drum sound like? When the pads and shoes wear down, it can result in a metallic grinding noise, as the backing plate starts making contact with the rotor or drum. Brake pads also have a metal wear indicator that drags on the rotors when the pads are worn out. This will make a grinding or squealing noise.
How often should brake drums be replaced? The housing of drum brakes is designed to be operable typically for around 150,000 to 200,000 miles, while the shoes are meant to last for 40,000 miles although they usually last the life of the vehicle if the car owner uses their brakes properly.
What can cause a brake drum to break?
A drum can crack when the parking brake is set while the brakes are extremely hot. The cooling drum contracted on the brake shoes with enough force to crack the drum.
Why do new cars still have drum brakes?
Modern lightweight cars still have rear drum brakes since the majority of the stopping work is done by the front brakes. Although perceived as “ancient”, drum brakes are sufficient for everyday driving and are easier to produce.
Why are drum brakes better than disc?
Drum brakes can provide more braking force than an equal diameter disc brake. 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.
Do you have to replace drums with shoes?
The drums only need replacing if they are deeply cracked or oversize. Properly adjusted drums last for several sets of shoes. The inner edge will need to be cleaned and gently chamfered off to allow the drum to slide back on easily when refitting.
How much is a rear drum brake job?
How much does it cost to replace a rear drum brake? It costs about $400 on average to replace a rear drum brake. The typical price range is between $200 on the low end and $600 on the high end.

Why do drum brakes last so long?
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. Drum brakes have a built-in self energizing effect that requires less input force (such as hydraulic pressure.
Are drum brakes more expensive to replace than disc brakes?
Less expensive. Drum brakes are less expensive than disc brakes, and this cost difference is reflected in the price of a new car. All other things being equal, a car with disc brakes on all four wheels will cost more than one with disc brakes on the front wheels and drum brakes on the rear.
How much should a full brake job cost?
Depending on the vehicle you drive, there can be a pretty big difference in pricing. The average brake pad replacement costs around $150 per axle, but these costs can rise to around $300 per axle depending on your vehicle’s brake pad materials. The least expensive brake pads use organic material.
Is it worth it to convert rear drum brakes to disc brakes?
Disc brakes dissipate heat better than drum brakes, so they’re able to stop faster. The brake pads on disc brakes are designed to provide more friction than the shoes or pads in drum brakes. Last, but not least, disc brakes stay drier in wet weather.
What are the disadvantages of drum brakes?
Drum brake disadvantages Excessive heating can happen due to heavy braking, which then can cause the drum to distort, and thus cause vibration under braking. Under hard braking, the diameter of the drum increases slightly due to thermal expansion, the driver must press the brake pedal farther.
How much does it cost to change rear drum brakes to disc?
Some kits such as semi-float kits and weld on kits take a little longer, too. Labor usually costs about $100/hour, so expect to pay about $400-$500 for labor.
Why are drum brakes cheaper?
Drum brakes are cheaper to manufacture than disc brakes. Rear drum brakes generate lower heat. Drum brakes have a built-in self energizing effect that requires less input force (such as hydraulic pressure. Wheel cylinders are simpler to recondition than disc brake calipers.
Why do pickup trucks have rear drum brakes?
The main reason why pickups have drum brakes, is due to the fact they are cost effective, require replacement less often, and because they just take less maintenance than their disc brake alternative.
