Modern Volkswagen vehicles use a hydraulic braking system with disc brakes at all four wheels. Dual-circuit master cylinders provide redundancy for safety. Pressing the brake pedal presses piston calipers against the rotor surface of each brake disc using hydraulic pressure. This friction slows the wheels.

Components involved in brake service include:

  • Brake pads: friction material pressed against rotors
  • Brake rotors: metal discs attached to wheels
  • Calipers: Housing containing brake pads
  • Brake fluid: hydraulic fluid that transfers pedal force
  • Hoses: Transfer brake fluid between components

Inspection Intervals

Volkswagen recommends inspecting brakes at every oil change, or approximately every 10,000 miles. The multi-point inspection checks pad wear, rotor condition, fluid levels, and hydraulic components. This interval may vary based on driving habits and conditions. More frequent brake inspections are wise for aggressive drivers.

Brake Pad Replacement

The friction material of brake pads wears down with use. Pads require replacement when worn to 2-3mm thickness. VW brake pads generally last 30,000-70,000 miles depending on driving, climate, and pad compound. Signs of worn pads include squealing/grumbling noises, vibration through the pedal or steering wheel, and longer stopping distances.

Replacing pads early preserves rotors. Waiting too long causes pads to completely wear away and metal backing plates to contact rotors, necessitating rotor replacement as well.

Rotor Inspection & Resurfacing

Inspect rotors at each pad change for wear and damage. Excessive runout, deep grooves, or cracking warrants replacement. With minor wear, rotors can be resurfaced on a brake lathe to renew the surface.

Rotors should be replaced in pairs on the same axle to prevent braking imbalance. VW specifies minimum rotor thicknesses remaining – any less means replacement is required.

Brake Fluid Flush

Brake fluid absorbs moisture over time which lowers boiling point and causes corrosion in the hydraulic system. VW’s factory service schedule calls for complete brake fluid flush every 2 years. More frequent flushing may be needed in humid climates.

Flushing involves draining the entire system and refilling with fresh fluid meeting Volkswagen’s strict specifications. Never mix fluid types or brands. Use only newly opened containers to avoid moisture contamination.

Bleeding Brakes

Air trapped in brake lines causes a soft, spongy pedal feel. Anytime lines are disconnected, bleed the system to remove air pockets. Bleeding releases air by pumping fluid through the lines.

VW utilizes a pressurized bleeding procedure with specialized equipment. DIYers can manually bleed brakes, but power bleeding provides the best pedal feel. Consult repair manuals for the proper bleeding sequence based on your Volkswagen model.

Brake Hose & Line Inspection

Rubber brake hoses expand slightly under pressure over years of use. This rubber expansion causes a spongy pedal effect. VW recommends replacing brake hoses every 3 years regardless of condition or mileage as preventive maintenance.

Also carefully inspect metal brake lines and fittings for corrosion or leaks during service. Any signs of damage or weeping require immediate replacement for safety.

Why Proper Maintenance Matters

While brakes are robust and durable components, lack of maintenance inevitably leads to failure. Gradual deterioration through factors like moisture contamination, worn rubber seals, and foreign debris in brake fluid will cause unsafe brake performance over time if neglected.

Staying ahead of issues via VW’s recommended brake service intervals reduces risks of failure and ensures short, straight stops in any situation. Don’t cut corners on these vital safety systems.

Warning Signs Of Brake Problems In Your Volkswagen

Be alert behind the wheel of your Volkswagen for any of these key warning signs that may indicate brake problems:

1. High Pedal Effort

Having to push the brake pedal harder than usual to slow down or stop often signals low hydraulic pressure. Causes can include fluid leaks, worn pads, or air in brake lines. Lack of braking power requires immediate attention.

2. Low/Spongy Pedal

A brake pedal that feels soft or sinks too close to the floor points to air trapped in the hydraulic lines. This brake system hazard provides slow, ineffective stopping and should be addressed urgently.

3. Grinding Noises

Scraping, grinding or other abrasive sounds when applying the brakes mean pad material is completely gone. Metal backing plates are contacting the rotor, damaging the surface. Replace pads immediately to avoid costly rotor replacement.

4. Pulsing/Vibration

A pulse through the pedal or vibration through the steering wheel under braking can signal warped rotors. It may also indicate deposits on rotor surfaces. Resurfacing or replacement of affected rotors is required to restore smooth operation.

5. Pulling To One Side

The brake system relies on equal friction on both sides. Pulling left or right under braking indicates an imbalance – often from contaminated pads or uneven rotor wear. The entire affected axle typically needs service to cure pulling.

6. Slow To Release

Brakes that seem to drag or release slowly after pedal pressure is released point to a sticking caliper or slide pin. Lack of proper caliper movement will accelerate wear and compromise safety.

Pay close attention to your Volkswagen’s brake feel and performance. Promptly investigating any warning signs prevents major problems and protects your safety on the road.

DIY Volkswagen Brake Pad Replacement

While brake service is best left to qualified technicians, replacing pads yourself can save money with careful work. Here is an overview of the process to safely change brake pads on Volkswagen models:

1. Gather Tools & Supplies

  • Floor jack & jack stands
  • Wheel chocks & lug wrench
  • Brake pad removing tool
  • C-clamp (for piston retraction)
  • Clean shop rags & brake cleaner
  • Replacement pads for your VW model

2. Lift & Support The Vehicle

  • Engage parking brake and chock drive wheels.
  • Loosen lugs on wheel where pads will be replaced.
  • Lift and support that corner with a jack stand.

3. Remove Wheels & Inspect Rotors

  • Fully remove lug nuts and wheel.
  • Inspect rotors for excessive wear, deep grooves, or cracks.
  • Measure rotor thickness.

4. Retract Caliper Pistons

  • Remove rubber caps from piston access ports.
  • Carefully retract each piston using a C-clamp.
  • Ensure each moves smoothly without cocking.

5. Detach Caliper & Remove Old Pads

  • Hang caliper using wire rather than letting it dangle.
  • Remove pad retaining clips, anti-rattle hardware as needed.
  • Slide out internal and external brake pads.

6. Clean Components

  • Clear away any debris on caliper, mount, and brake shield.
  • Flush caliper bore and lubricate slides/pins with silicone paste.

7. Install New Pads

  • reference markings to determine pad orientation.
  • Press pads fully and evenly into place.
  • Reinstall retaining clips, springs, and hardware.

8. Remount Wheels & Caliper

  • Torque lugs to spec with proper star pattern.
  • Remove wire and remount caliper securely.
  • Repeat process on remaining wheels.

Take care when depressing brake pedal to bring pads to proper position. Also properly bleed brakes if any lines were opened to complete service.

Why Your Volkswagen Shakes When Braking

Brake system problems that cause your Volkswagen to shake or vibrate when slowing down or stopping need prompt attention. Several key issues can cause brake vibration:

1. Warped Brake Rotors

Heat and stress over time can warp brake rotors resulting in thickness variations called runout. As the pads contact high and low spots during braking, vibration occurs. Resurfacing or replacing rotors cures it.

2. Worn Brake Pads

When pads wear thin, the backing plate contacts rotors causing harsh vibrations. Uneven pad deposits on rotors can also cause pulsing. Thorough pad replacement and rotor resurfacing fixes this.

3. Contaminated Brake Pads

Oil, grease, or other debris smeared on brake pads reduces friction unevenly. This can make the pads “stick-slip” against the rotor surface leading to vibration. Thorough cleaning or pad replacement is needed.

4. Caliper Issues

Sticking, frozen, or non-functioning caliper pistons prevent even pad pressure on both sides of a rotor. This imbalance generates shaking. Caliper rebuilding or replacement resolves it.

5. Wheel Bearing Wear

Worn wheel bearings allow excessive rotor and hub movement. This unstable environment contributes to shaking when brakes are applied. Bad bearings require replacement to reduce vibration at all speeds.

Conclusion

Diagnosing the specific cause of your Volkswagen’s brake vibration is key to the right repair. A few common issues like contaminated pads can be fixed quickly. But extensive damage may require rotor, caliper or wheel bearing service to restore proper brake operation.
