Quick Answer: Why Brake Problems?
Most brake problems stem from worn brake pads (60%), which cause squealing sounds when wear indicators are active. Other common issues include warped rotors (20%) causing vibrations, brake fluid problems (10%) resulting in a spongy pedal, and caliper issues (5%) causing pulling to one side.
Common Causes & Solutions
Worn Brake Pads
60%Most common issue. Squealing noise indicates wear indicators are active. Replace before metal-on-metal contact.
Warped Rotors
20%Causes vibration when braking. Usually from heat buildup or aggressive braking. May need resurfacing or replacement.
Brake Fluid Issues
10%Low or contaminated fluid causes spongy pedal. Dark fluid needs flushing. Air in lines requires bleeding.
Caliper Problems
5%Stuck or leaking calipers cause uneven braking and pulling. Can damage rotors if not fixed promptly.
Master Cylinder Failure
3%Pedal sinks to floor or feels soft. Critical safety component - immediate repair needed.
Other Issues
2%Includes ABS problems, brake line leaks, or parking brake issues. Professional diagnosis required.
Identify Brake Problems by Sound
High-Pitched Squealing
Wear Indicators Active
Brake pads have 20-30% life remaining
⚠️ Schedule replacement within 1-2 weeks
Grinding/Scraping
Metal-on-Metal Contact
Pads worn completely - damaging rotors
🚨 STOP DRIVING - Emergency repair needed
Hissing/Whooshing
Brake Booster Issue
Vacuum leak affecting brake assistance
ℹ️ Harder pedal effort - repair soon
Vibration/Pulsing
Warped Rotors
Heat damage or uneven wear on rotors
⚠️ Resurface or replace rotors
🚨 Emergency: Stop Driving Immediately If
Brake pedal goes to the floor
Grinding noises when braking
Brake warning light is on
Car pulls hard when braking
Brake fluid leaking under car
Burning smell from wheels
Brakes feel completely spongy
Stopping distance increased
Emergency Tips: Use parking brake gradually • Pump brakes if spongy • Shift to lower gear • Find safe place to stop
Brake Repair Cost Guide
| Service | Cost Range | Frequency |
|---|---|---|
| Front Brake Pads | £120 - £240 | 25,000 - 50,000 miles |
| Rear Brake Pads | £95 - £200 | 30,000 - 60,000 miles |
| Rotor Replacement | £200 - £400 | 50,000 - 100,000 miles |
| Complete Brake Service | £320 - £640 | As needed |
| Brake Fluid Flush | £65 - £120 | Every 2-3 years |
| Caliper Replacement | £240 - £640 | 100,000+ miles |
💡 Pro Tip: Regular maintenance prevents expensive repairs. Address squealing immediately to avoid rotor damage.
DIY Diagnosis Steps
Visual Brake Pad Check
Look through wheel spokes at brake pads. They should be at least 1/4 inch thick. If you see metal backing plates, pads are worn out.
Test Brake Pedal Feel
With engine running, press brake pedal firmly. It should feel solid and not sink to the floor. Spongy feel indicates fluid or air issues.
Check for Brake Noises
Drive slowly and apply brakes. Listen for squealing (worn pads), grinding (metal contact), or clicking (loose components).
Test for Pulling
On a safe, straight road, gently brake. Car should stop straight. Pulling to one side indicates uneven brake wear or stuck caliper.
Inspect Brake Fluid
Check master cylinder reservoir. Fluid should be clear/light amber, not dark. Low fluid may indicate worn pads or leaks.
Frequently Asked Questions
What are the warning signs of brake problems?
Common brake warning signs include squealing or grinding noises, spongy brake pedal, vibrations when braking, brake warning light, pulling to one side, and longer stopping distances.
How much do brake repairs typically cost?
Brake repair costs vary: Brake pad replacement (£120-£320), rotor replacement (£160-£480), full brake job (£240-£640), brake fluid flush (£65-£120), caliper replacement (£240-£640).
How often should I replace my brake pads?
Brake pads typically last 25,000-70,000 miles depending on driving habits, brake pad material, and vehicle type. City driving and aggressive braking reduce pad life significantly.
Is it safe to drive with brake problems?
Never drive with severe brake issues like grinding noises, spongy pedal, or brake warning lights. Minor squealing may allow careful driving to a repair shop, but prioritize safety and stop driving if braking performance is compromised.
