Zimmermann's Systematic Approach to Quieter Brakes

Brake noise is a common complaint among drivers, often leading to frustration and frequent visits to the mechanic. However, Otto Zimmermann GmbH, a leading manufacturer of brake components, has developed a comprehensive approach to tackle this issue. By implementing a range of supplemental measures, Zimmermann enhances the noise characteristics of their brake pads, ensuring both maximum performance and a high level of driving comfort.

Key Highlights

Damping plates and adhesive layers reduce vibrations by acting as shock absorbers.
Intermediate layers improve heat transfer and increase shear strength.
Custom bevels and grooves suppress vibrations for smoother braking.
Additional damper weights lower resonant frequency to eliminate noise.
Directional pads align with the disc for optimal performance.
Friction material mixture is tuned for disc compatibility.
Correct installation is emphasized with workshop guidance.

Arrows on the backing plate, which indicate the direction of rotation of the brake disc, serve as an aid for the correct installation of Zimmermann brake pads.

The curved cut-out on the backing plate is an indication of a directional brake pad.

Chamfers and grooves in the friction material reduce frequency peaks during the braking process.

Additional damper weights (tilger weights) serve to reduce oscillations and vibrations by lowering the resonance frequency of the caliper.

Advanced Noise Reduction Techniques

Otto Zimmermann GmbH employs innovative methods to ensure quieter braking. Damping plates and adhesive layers are attached to brake pads, absorbing vibrations like cushions to prevent noise. Intermediate layers sit between the backing plate and friction material, managing heat and boosting stability by enhancing shear strength.

The friction material’s design is key. Custom bevels, or specially shaped edges, control how pads meet the disc, reducing vibrations in critical ranges for a quieter stop. Grooves carved into the material adjust its natural frequency, further cutting noise. In some cases, additional damper weights—also called tilger weights—target oscillations, lowering the caliper’s resonant frequency to silence unwanted sounds.

Precision and Compatibility

Zimmermann uses directional pads, which must match the brake disc’s rotation for smooth operation and even wear. Arrows or curved cut-outs on the backing plate guide mechanics during installation. The friction material mixture is carefully crafted and tested, ensuring it pairs perfectly with the brake disc material. Extensive testing, even under extreme conditions, guarantees reliability.

Installation Matters

Even top-tier brakes can squeak if installed incorrectly. Zimmermann provides workshops with technical sheets and videos, stressing proper techniques like observing rotation direction and using metal-free lubricants. This systematic approach not only boosts comfort but also reduces complaints, keeping drivers satisfied.
