Precision-machined from high-quality cast iron, Sebro brake discs deliver excellent heat dissipation, consistent braking performance and smooth pedal feel while maintaining full compatibility with Porsche's advanced ABS, Porsche Stability Management (PSM) and electronic brake systems. Whether used for everyday road driving or spirited performance driving, these OE-quality brake discs provide the confidence and stopping power your Porsche deserves.
What Do the Front Brake Discs Do?
Front brake discs are one of the most important safety components on your Porsche. As the brake pads clamp against the rotating discs, friction is created to slow the vehicle while converting kinetic energy into heat.
Their primary functions include:
- Providing the braking surface for the front brake pads.
- Dissipating extreme braking temperatures.
- Delivering smooth and consistent stopping performance.
- Maintaining braking stability during repeated heavy braking.
- Supporting Porsche ABS and PSM systems.
- Providing precise pedal feel and maximum driver confidence.
Because the front axle performs the majority of the braking effort, high-quality brake discs are essential for maintaining Porsche's renowned braking performance.
Why Do Front Brake Discs Wear Out?
Brake discs are consumable service components that naturally
wear through continual use. Common causes include:
- Constant friction from the brake pads.
- High operating temperatures.
- Fast road and spirited driving.
- Track day use.
- Natural reduction in disc thickness.
- Brake pad wear.
- Corrosion from moisture and road salt.
- Repeated heat cycles over high mileage.
As the braking surface wears, performance can gradually decline, resulting in increased stopping distances, vibration or brake noise.
When Should the Front Brake Discs Be Replaced?
Replacement is recommended whenever:
- The brake discs reach Porsche's minimum thickness specification.
- Heavy scoring or grooves develop.
- Brake vibration or pedal pulsation occurs.
- Heat cracks become visible.
- Excessive corrosion affects the braking surface.
- New brake pads are being installed on worn discs.
- During a complete front brake overhaul.
For optimum braking performance, Porsche specialists recommend replacing both front brake discs together with a new set of brake pads and brake pad wear sensors.

What This Product Does
The rotor turns with the wheel, allowing the caliper to press the pads against its braking faces. The resulting friction converts movement into heat as the vehicle slows. Matching the disc to the vehicle's brake specification is essential when selecting a replacement.
Functions
- Offers braking faces for pad contact.
- Operates alongside the rear pads and caliper.
- Transfers heat produced by friction.
Technical Details
- Installation position: rear axle.
- Outside diameter: 299mm.
- Specified thickness: 24mm.
- Supplied OE references: 95135204102, 95135204105 and 95135204106.
- The supplied diagrams identify 95135204106 for 964 Carrera 4 from 1989 onwards, Carrera 2 from 1992 onwards, Carrera 2 1989–94 and 968 1992–95 assemblies.
- Each referenced assembly specifies two discs; this is an assembly quantity, not a statement of pack contents.
Symptoms of Fault
- Judder or pulsation when applying the brakes.
- Grooved braking faces or raised outer edges.
- Localised heat marks or visible cracking.
- Corrosion affecting the contact faces or ventilation passages.
- Scraping, grinding or squealing during braking.
- Uneven braking or a tendency to pull sideways.
Why Replacement Matters
Inspection may identify disc wear, cracking, substantial corrosion or damage that requires renewal. Noise and vibration can also involve pads, calipers or other brake components, so establish the cause before replacing the rotor. Confirm the applicable wear limits and inspect the associated components during the repair.
FAQs
Is this suitable for M030-equipped vehicles?
No. Not suitable for cars with M030.
How large is the disc?
The supplied specification gives an outside diameter of 299mm and a thickness of 24mm.
Does the diagram quantity mean two discs are included?
No. It records the number used in the assembly and does not establish the supplied pack quantity.
Which details should be confirmed?
Match the vehicle's year, variant, brake equipment and applicable OE number. The model family alone is insufficient to establish suitability.
