Brake Discs

Product Overview.

Alto Brake Discs are precision-engineered to deliver reliable braking performance, durability, and safety across a wide range of passenger vehicles.

Manufactured from high-quality cast iron and produced using advanced machining processes, Alto brake discs are designed for optimal heat dissipation, minimal vibration, and consistent braking stability.

Each disc undergoes strict quality control procedures to ensure dimensional accuracy, balanced performance, and long service life. Alto brake discs are designed to pair perfectly with high-quality brake pads, providing smooth braking and dependable stopping power.

Vehicle Coverage

Brake disc coverage across the SA vehicle parc.

Alto Brake Discs cover front and rear axle applications across passenger cars, SUVs, and light commercial vehicles common on South African roads. Each disc is dimensioned to the original equipment geometry — outer diameter, thickness, vent type, hub bore, and bolt pattern all match OE.

European passenger
VW Group, BMW, Mercedes-Benz, Audi, Mini, Opel, Renault, Peugeot, Citroën, Fiat, Alfa Romeo, Volvo. Solid and vented variants covered.
Asian passenger
Toyota, Hyundai, Kia, Mazda, Nissan, Honda, Mitsubishi, Suzuki, Subaru.
Bakkie / 4x4
Toyota Hilux, Ford Ranger, Isuzu D-Max / KB, Mitsubishi Triton, Nissan Navara, VW Amarok — vented front discs and rear solid/vented variants.
Light commercial
Common LCV platforms with extended outer-diameter discs to match the chassis spec.
Manufacturing & Specification

Cast iron, precision-machined, balanced.

A brake disc fails through three mechanisms: cracking, warpage, and uneven wear. Alto discs are engineered to OE specification against all three:

High-quality cast iron
Manufactured from cast iron grades suited to brake disc duty — correct carbon content for thermal stability, appropriate flake graphite structure for heat dissipation, no inclusions or porosity that would cause cracking.
CNC-machined to OE dimensions
Outer diameter, friction-surface width, vent geometry, hub bore, and bolt-pattern PCD all machined to the original equipment specification. Critical for correct fitment and for matched braking torque front-to-rear.
Run-out within OE tolerance
Lateral run-out (the “wobble” measured at the friction face when the disc spins) is held within OE tolerance. Excessive run-out is the most common cause of disc thickness variation, which presents as pulsing pedal under braking.
Balanced
Each disc is balanced before packaging — relevant on higher-speed applications where an imbalanced disc causes vibration through the steering at motorway speed.
Solid and vented variants
Full range of solid (rear-axle on most light vehicles) and vented (front-axle and heavy-duty rear) configurations. Vent direction and vane count match OE pattern.
High-carbon options
Selected performance and premium applications supplied in high-carbon cast iron specification — better resistance to thermal cracking under repeated heavy use.
Trade FAQ

Common questions about brake discs.

Solid vs vented discs — what is the difference?
A vented disc has internal vanes between the two friction faces that pump air through the disc as it rotates, dissipating heat. A solid disc has a single thickness of cast iron. Vented discs are used on front axles (which do most of the braking work and generate the most heat) and on high-load rear axles. Solid discs are used on rear axles of most light passenger vehicles. Always match the OE specification for that vehicle — do not swap solid for vented or vice versa.
Should brake discs always be replaced in pairs?
Yes — left and right on the same axle. A new disc on one side and a worn disc on the other gives uneven braking torque, which the vehicle experiences as pulling under braking and uneven pad wear. Always supply discs by the pair to retail customers, even if the customer only asks for one side.
Can a brake disc be machined or skimmed?
In principle yes, but the disc must remain above the minimum-thickness specification cast or stamped on the disc itself. In modern practice, with disc replacement priced competitively, most workshops replace rather than skim — skimming labour plus the risk of going under-thickness rarely justifies the saving. Always check the minimum thickness before considering a skim.
What is the minimum disc thickness?
It is stamped or cast on the disc itself — typically on the hub face or the outer rim. The number is given in millimetres and is the absolute floor below which the disc must be replaced. Below that thickness, the disc cannot dissipate enough heat and is at risk of cracking under heavy use.
What causes warped discs / pulsing pedal?
In most cases, what mechanics call “warping” is actually disc thickness variation caused by uneven pad deposits on the friction face — which itself is usually caused by overheating combined with sitting the vehicle with the pads against a hot disc (parking after a hard descent, for example). True thermal warping is rare on quality discs installed correctly. Specify quality discs, correct bedding-in, and educate retail customers on heat management.
How do I cross-reference Alto disc part numbers?
Use the Eurospares catalogue picker on this site — enter the vehicle Make, Model, and Engine, and the catalogue returns the matching Alto part number. Cross-references for OE numbers and competitor codes (Ferodo, Brembo, ATE, Textar, and others) are built into the picker.
