How to Fix a Car That Has Poor Braking Performance
I've always been someone who takes car maintenance seriously. It's one of those things that can't be ignored, especially when it comes to the braking system. After all, the brakes are the most critical part of your car when it comes to safety. A while ago, I noticed that my car's braking performance had been feeling off. The car wasn't stopping as quickly, and the pedal felt unusually soft. I realized it was time to figure out what was wrong and fix it before it became a bigger problem. Here's what I learned along the way about fixing a car with poor braking performance, and how I managed to get my car back in tip-top shape.
The first thing I did was to try to understand what could cause poor braking performance. I had noticed that the brakes were less responsive, and the car required more distance to stop. At first, I thought it might just be a simple issue, but as I looked deeper, I realized that braking issues could be caused by a variety of factors. If you're facing the same issue, there are several things you can check before heading to a mechanic. Here's a breakdown of how I approached the problem.

1. Checking the Brake Fluid Level
One of the first things I checked was the brake fluid. It’s one of the most common culprits when it comes to poor braking performance. Low brake fluid can cause a soft brake pedal and poor braking response. The brake fluid reservoir is easy to find in most cars. You can usually see it near the back of the engine bay. On my car, the brake fluid was slightly below the "MIN" line, so I topped it up with the correct brake fluid type. It's crucial to use the right kind of fluid to avoid damaging the braking system.
Once I filled the brake fluid, I pumped the brake pedal a few times. It was still soft, which meant that the brake fluid alone wasn't the whole problem. I realized that if the fluid level had dropped, there might be a leak somewhere in the braking system, so I knew I had to dig deeper.

2. Inspecting the Brake Pads
Next, I decided to check the brake pads. Worn-out brake pads are a common issue and can significantly affect braking performance. When brake pads are too thin, they can't create enough friction to stop the car effectively. I took a quick look at the pads through the wheel spokes and noticed they were quite worn. I knew that I had to replace them to get the car's braking performance back to normal.
Replacing brake pads isn't as hard as it might sound, and I had done it before. But it's important to make sure that you replace them with the right type of pads for your car model. The quality of the pads is also crucial—cheaper options might save you money in the short term, but they won't last as long or perform as well. So I opted for premium ceramic pads, which are quieter and have better stopping power.
3. Examining the Brake Discs
While replacing the brake pads, I also decided to check the brake discs (or rotors). Worn-out or damaged rotors can cause uneven braking, leading to vibrations when you press the brake pedal. In my case, the discs had some slight grooves and scoring, but they weren't too bad. I was able to get away with just resurfacing the rotors to make sure they were smooth enough for the new brake pads.
If the rotors are seriously worn, they might need to be replaced altogether. Resurfacing them at a machine shop is often the most cost-effective solution if the damage isn't too severe. I did this myself by carefully measuring the rotor thickness, and it worked well for my situation. If you're unsure about how to check the rotors, it’s a good idea to consult a professional mechanic.
4. Bleeding the Brakes
After topping up the brake fluid, replacing the pads, and resurfacing the rotors, I still noticed the brake pedal was a bit soft. That told me there might still be air in the brake lines, which would affect braking performance. So, I decided to bleed the brakes. This process involves removing any air from the brake lines and ensuring that the brake fluid is circulating properly. It’s a fairly simple procedure, but it requires some patience and care.
To bleed the brakes, you need a helper, as it’s a two-person job. One person will pump the brake pedal while the other opens and closes the brake bleeder valve on each wheel. The goal is to remove any trapped air and get fresh brake fluid into the lines. Once I finished this process, I noticed the brake pedal was much firmer, and braking performance improved significantly.
5. Looking for Leaks in the Brake System
After everything was back in place, I took the car out for a test drive to see how the brakes were performing. They felt better, but I wanted to make sure there were no leaks in the system, as low brake fluid can sometimes indicate a leak. I inspected the brake lines, calipers, and wheel cylinders for any signs of leakage. Fortunately, everything looked fine, but if you suspect a leak, it’s important to address it right away. Brake fluid leaks can lead to brake failure, which is obviously a huge safety risk.
6. Replacing the Brake Master Cylinder (if Needed)
If you've checked the fluid levels, the pads, and the lines, and your brakes are still not performing well, the next thing to consider is the master cylinder. A faulty master cylinder can cause a soft or spongy brake pedal and prevent the brakes from engaging properly. Replacing a master cylinder can be more complicated, and it often requires a professional mechanic to ensure the job is done safely.
In my case, after addressing all the previous issues, my brakes were working much better, and I didn’t need to replace the master cylinder. However, if you’re still experiencing poor braking performance despite all efforts, it’s a good idea to have a mechanic check the master cylinder and other brake components.
7. Final Test Drive
Once all the repairs were done, I took the car on a final test drive to ensure the brakes were functioning properly. The pedal felt firm, the car stopped quickly and evenly, and there were no strange noises or vibrations. It was a great feeling to know that my brakes were back in top condition, and I could drive safely again.
If you’re ever in a situation where you feel your car’s braking performance isn’t up to par, don’t ignore it. Poor brakes are a major safety hazard, and it’s important to address the issue right away. Whether you’re a seasoned DIYer or you prefer professional help, getting your brakes fixed is crucial for your safety and peace of mind.
In case you need any professional assistance with towing your vehicle for repairs, or if you need help getting your car to a shop, I recommend contacting Rescue & Towing for quick and reliable service. They specialize in towing and emergency roadside assistance, so you can get your car fixed and back on the road in no time.
