When I was a teen I had a Ford Elite. I changed the front brakes on my car. I started to hear a whining noise every time I applied the brakes so I knew something was wrong. I was relieved to find out that my brakes were suppose to make that sound and weren’t ruining my rotors (discs).
Drum brake pads typically last about 35,000 – 45,000 miles and may last up to 100,000. If you commute daily get them inspected every 6 months. You should replace them or get them checked when:
- Your braking starts taking longer;
- You hear a whining or scrapping sound from the brakes;
- Your car starts to vibrate when braking;
- Your brake pedal or hand brake feels loose;
- When you or a mechanic inspects them and they are 1/16 of an inch thin.
Checking to see if the drum brakes need replacing (also called shoes) can be done at home or by a mechanic. If you don’t have experience working on cars or the right tools then a mechanic would be best. If you want to do it yourself ensure you have time, patience, and the right tools.
Checking the Drum Brake Pads
Before you do anything it best to find out if your brakes need replacing or if there’s another problems causing the brakes to act strangely.
Checking the brake drums pads shouldn’t be too hard. It requires you to take off the wheel and the brake drum.
You’ll need to have:
- Jacks stands;
- Floor Jack;
- Tire Chocks;
- Possibly a Hammer.
You can watch this video for more details about how to safely remove the tire and brake drum.
Once your tire and brake drum are off you will be able to check your brake pad thickness. If they measure more than 1/4 inch thickness then they are still good. Once they reach 1/8 of an inch it’s probably best to replace them even if they could go down to 1/16 of an inch.
If you decide that you want to try replacing your own drum brake pads, then you will need to make sure you have all the time, equipment, tools, and parts you need before you begin. Otherwise you could be stuck without a car for a while.

– Measure the thickness of the old shoes with a digital micrometer and change them if the thickness is less than 1/16th. Make a thorough check for the cracking, scoring or grooving and check the wheel cylinders. If the brake fluid is leaking, replace it.
– By using needle-nose pliers, remove the shoe retaining springs. If you loosen the top spring, it will loosen the overall tension, and you can easily remove the lower springs. If the shoes are tensioned with pins and washers, pull them free by using needle nose pliers
– Check for any leakage and if found, replace the brake wheel cylinders, immediately. Next, go in for reassembly.
– Remove the retainer clip of the parking brake cable by twisting it with a pair of pliers or by prying with flat- head screwdriver.

Now that you are conversant with the replacement of drum brakes, it is pertinent for you to be aware of the utilities and advantages of the best brake controllers. These are especially beneficial for towing a vehicle. The brake controller is an external device, installed on the dash of the vehicle that is towing another vehicle. When the driver of the towing vehicle applies the brake, a message is electronically transmitted to the brakes of the towed vehicle that it must stop.
When the towing vehicle applies the brake, the towed vehicle continues to move at the same velocity and causes a domino effect which is a great threat to the safety of both the vehicles. There are two kinds of the brake controller. The Time-delayed one applies a pre-determined pressure on the brakes of the towed vehicle. The second category is called Proportional and is comparatively cheaper.
According to your budget and need, you can opt for any one of the following well-performing brake controllers:
- Reese Towpower 850711; Brakeman;
- Tekonsha 90885, Prodigy;
- Hopkins 47284, Reliance;
- Tekonsha 90195 P3;
- Draw-Tite 201911-Stop.
If you are a conscious vehicle owner, you know how essential it is to use quality brake fluid. It makes the brakes of your vehicle operate perfectly and thus provide absolute safety, while you are driving your vehicle. When you apply the brake, heat is generated. If your brake components are overheated, there is every possibility of brake failure. Brake fluid prevents overheating. Other functions of brake fluid are it keeps the moving parts perfectly lubricated and protects them from corrosion. It reduces the wear and tear of the moving components.
There are mainly three types of brake fluids. They are:
- DOT 3 is Glycol-based that attracts water and has the lowest boiling point;
- DOT 4 too is Glycol-based but has a little higher boiling point;
- DOT 5 is silicon based and does not attract water. It has a higher boiling point.
You can choose the best brake fluid out of the following:
- Prestone AS 400 which is DOT 3 type;
- ATE 706202 TYP 200 which is DOT 4 type;
- Motul RBF 600 which is DOT 4 type.
The brake is the life-saving components of your vehicle. You should know to replace the drum brakes as a professional. Never compromise on price when it comes to the use of brake fluid. If you are vehicle uses trailers, it will be your prudent decision to make use of a brake controller.
