What This Product Does:
- Replaces worn or heat-damaged rear brake discs
- Installs fresh OEM-quality rear pads for improved stopping power
- Restores proper pad wear monitoring via a new sensor
- Reduces brake noise, vibration, and rear-end instability
- Improves stopping distance and pedal feel
- Restores safe, consistent braking performance on the rear axle
Symptoms Of Wear Or Failure:
- Squealing or screeching sounds from the rear when braking
- Grinding noises (pads worn to metal backing)
- Brake pedal pulsation or vibration during braking
- Soft or inconsistent pedal feel
- Longer stopping distances
- Brake warning light triggered by worn pads or a failed sensor
- Visible rotor damage: grooves, scoring, heat spots, blueing, cracks
- Uneven or excessive brake dust on rear wheels
- Rear instability under braking
Why Replacement Matters:
- Rear brakes are crucial for vehicle stability during braking. New discs and pads ensure predictable, safe stopping.
- Fresh rotors and pads bring back OEM braking power, pedal feedback, and smooth operation.
- Worn pads can gouge rotors; warped rotors ruin new pads. Replacing both avoids unnecessary repair costs.
- New components reduce brake squeal, vibration, and pulsation commonly caused by worn rear rotors.
- A new wear sensor keeps the brake-warning system working correctly.
- Replacing discs, pads, and sensors at the same time reduces labour costs and ensures even wear.
- Proper brake maintenance helps preserve performance, reliability, and resale value.

SHW PERFORMANCE, one of the world's leading brake disc manufacturers supplying directly to OEM, with product featured as standard equipment on many of today's new performance vehicles.
THE ONLY TRUE REPLACEMENT.
NOTHING LESS THAN A TRUE FACTORY EQUIVALENT
SHW PERFORMANCE produces both one and two piece, ventilated disc brake rotors to cover a wide range of vehicle applications.The vehicle application automatically dictates which style, composition and type of disc brake rotor is available, as SHW only offer a genuine direct replacement for the factory supplied disc.For lesser performance orientated vehicles, a ventilated monoblock disc brake rotor produced from cast iron will more than suffice. For vehicles placing greater demand on the needed stopping power, a lightweight, composite, fully floating two-piece design is often preferred (the style of which is referred commonly as a peg or pin drive system).
PERFORMANCE UNDER PRESSURE.
CONSISTENT RELIABILITY AND PERFORMANCE UNDER THE MOST DEMANDING OF CONDITIONS
Quality is a key ingredient from which to guarantee long term repeated reliability. SHW products are built to carry the high expectations required by exacting OEM standards and exceed them where possible.
PATENTED DESIGN PIN-DRIVE SYSTEM.
FROM WEIGHT REDUCTION TO IMPROVED COOLING, DISCOVER THE BENEFITS OF THE SHW PIN-DRIVE BRAKE ROTOR SYSTEM
Innovation, sustainability, added value. Welcome to SHW's patented Pin-Drive system, a substantial step forward in the future of braking.
SHW's Pin-Drive system carries many benefits when compared to conventional methods of disc brake rotor design. So, what is 'Pin-Drive' and why is it advantageous over a one-piece disc brake rotor?
The Pin-Drive system is a two piece fully floating disc brake rotor. The friction ring is connected to the central aluminium rotor bell by means of stainless steel pins which are cast into the assembly during the manufacturing process. The purpose behind the design is to offer a range of advantages:
- Up to 5.5lbs of weight reduction (rotating and unsprung weight) per disc compared to Monoblock.
- Reduced thermal strain thanks to the friction ring having more freedom to expand and contract.
- Low brake fading properties.
- Improved durability.
- Enhanced brake comfort thanks to optimised thermal conditions.
- Optimal curved vane design that maintains structural strength while improving noise dampening.
UNPARALLELED COOLING ADVANTAGES.
MAINTAIN OPTIMUM BRAKING PERFORMANCE FOR LONGER WITH IMPROVED COOLING PROPERTIES.
As well as a reduction in unsprung weight and improved braking characteristics, SHW's Pin-Drive design also prides itself on offering unbeatable cooling advantages, just one of the reasons why it has become the first choice for many OEM's.
Unlike other brake manufacturers, SHW developed a PATENTED improvement of the disc construction by offsetting the pin connection of the friction ring to the aluminium disc bell away from the center to the edge, which results in huge cooling gains.
By offsetting the pin connection of the friction ring to the aluminium bell the cooling channels running centrally through the rotor see a huge increase in accessibility and cooler air flow. This advantageous design offers up to a 50% cooling advantage gain when compared to traditional designs.
Allowing a greater flow of air, heat generated on the surface of the friction ring (via the brake pads clamping down under braking) is carried away faster and more efficiently, dramatically reducing inner core and surface temperatures across the complete disc brake rotor. In addition, due to the unique patented design, further weight savings are achieved thanks to a shallow aluminium disc bell.
THE IMPORTANCE OF AIR FLOW.
WHEN AIR FLOW IS PARAMOUNT TO PERFORMANCE. THE LOWER THE OPERATING TEMPERATURES, THE HIGHER THE PERFORMANCE.
The cold air is traditionally fed via air ducts located either in the front bumper, or channeled through pathways on the underside of the vehicles under tray. As the cold air enters the rear of the disc bell, it passes through vanes between the two brake rotor faces. The cooler air helps to reduce temperatures from the very core of the brake disc by collecting heat and carrying it outwards, away from the brake disc assembly and eventually venting back out into the passing air flow found circulating the inner wheel.
