Brake Problems: What Causes Them and How to Fix Them

If your car feels wobbly when you press the pedal, makes squealing noises, or takes longer to stop, you’re probably dealing with brake problems. Most drivers ignore early warning signs because they think brakes are a set‑and‑forget part. In reality, brakes are one of the few components that need regular checks – just like your oil or tyres.

There are three main culprits behind brake issues: worn pads, warped rotors, and leaking fluid. Worn pads are the most common and show up as a grinding or squealing sound. Rotors can warp after heavy braking or when they get too hot, which creates a pulsating pedal. Fluid leaks usually come from the master cylinder or brake lines and can make the pedal feel spongy.

Common Signs Your Brakes Need Attention

Start listening for any change in how the brake pedal feels. A soft, low‑bottomed pedal often means low fluid or air in the system. If you hear a high‑pitched squeal, it’s usually a wear‑indicator shim rubbing against the rotor – that’s a clear sign the pads are near the end of their life.

Another red flag is vibration when you brake. If you feel a shudder through the steering wheel, the rotors are likely warped and need resurfacing or replacement. Finally, a burning smell after a long downhill drive indicates the brakes are overheating, which can damage pads and rotors quickly.

Rear Brake Pads: Can You Change Only the Back Ones?

Many owners wonder if they can just replace the rear pads and leave the front ones alone. The short answer: you can, but only if the front pads are still in good shape. Replacing only the rear pads is safe when the front pads have plenty of life left and the rotors are even.

When you change rear pads, inspect the rear calipers for sticking pistons. A stuck caliper can cause uneven wear and lead to pulling to one side. Also, check the brake fluid level and look for any leaks around the rear brake lines. If you find any issues, it’s better to address them all at once rather than doing a partial fix.

For most drivers, a balanced brake system feels smoother and stops more predictably. If you’re unsure about pad thickness, measure them with a ruler – most pads should be at least 3 mm thick. Anything thinner means it’s time for a full set.

DIY‑friendly tips: loosen the caliper bolts, compress the piston with a C‑clamp, then slide the old pads out and fit the new ones. Remember to torque the bolts to the manufacturer’s spec – usually around 30 Nm for most cars. After fitting, pump the brake pedal a few times to seat the pads before you drive off.

If you’re not comfortable doing the job yourself, a local garage can replace the rear pads and check the front ones for you. Many shops, including Northwich Tyres Centre, offer a quick safety check and will let you know if the front pads need attention too.

Bottom line: don’t ignore brake noises or a soft pedal. Regular inspections keep you safe and save money by avoiding costly rotor replacements later. Keep your brake fluid clean, replace pads before they hit the wear limit, and make sure both front and rear systems are balanced. Your car will stop when you need it to, and you’ll drive with confidence.
