Wholesale Brake Rotors for Automotive Aftermarket Buyers
Precision-machined brake rotors for passenger cars, SUVs, pickups and light commercial vehicles, available in solid and vented constructions. Each reference is produced to application-specific diameter, thickness, overall height, center bore and bolt configuration, with lateral runout under 0.05 mm and optional zinc or geomet finishes for different aftermarket programs.
Brake Rotor Types
Brake Rotor Types for Different Braking Applications
Brake rotor construction varies according to vehicle design, axle position and braking requirements. We supply solid, vented and performance-style brake rotors in application-specific dimensions for automotive aftermarket programs.
Solid Brake Discs
A single solid casting with no internal vanes. Heat leaves through the outer surfaces alone, which is enough wherever braking energy stays low. Standard on rear axles and on smaller passenger cars.
- Structure：Single casting
- Casting：Grey cast iron
- Finish：Plain or coated
Vented Brake Discs
Two friction faces separated by internal cooling vanes. Rotation draws air through those vanes and pulls heat out from the centre, so the friction surface stays cooler under repeated braking. The standard fitment on front axles, SUVs and pickups.
- Structure：Internal vanes
- Casting：Grey or high-carbon
- Finish：Plain or coated
Drilled & Slotted Discs
Cross-drilled holes and machined slots cut into the friction face. The openings give gas, dust and water a path off the surface, so the pad keeps clean contact under hard braking. Fitted mainly to front axles on sport and upgrade applications.
- Structure：Drilled & slotted
- Casting：High-carbon
- Finish：Coated or painted

For wholesale orders, buyers can mix different brake part numbers and quantities in one purchasing list, as long as the combined order reaches a total of 100 sets.
Global Export Experience
We have experience supplying brake parts to overseas buyers and understand the standards, expectations and communication needed for international business.
Manufacturing Process
Brake Disc Manufacturing, From Molten Iron to Packed Carton
A brake disc is decided at the foundry, not at final inspection. As a brake disc manufacturer running its own foundry and machine shop in China, we hold every stage below in house — here is the full sequence and what is controlled at each step.
01
Iron Melting
Scrap steel, pig iron and alloys are melted and the chemistry is adjusted to the required grade before any iron is poured.
02
Moulding & Pouring
Iron is poured into sand moulds shaped to the reference, forming the raw casting including the internal cooling vanes.
03
Shakeout & Ageing
Castings cool, come out of the moulds and are aged so internal stress is released before it can be locked into a machined disc.
04
Rough Turning
Excess material comes off and the basic diameter, thickness and mounting faces are established.
05
Finish Turning & Grinding
Friction faces and the hub mounting face are finished in the same setup, which is what keeps the disc running true once fitted.
06
Drilling & Slotting
Bolt holes are drilled to the pitch circle; cross-drilled holes and slots are machined on the references that take them.
07
Balancing & Coating
Discs are dynamically balanced, then coated or painted — hat and edges included, since that is where rust shows first.
08
Inspection & Packing
Runout, thickness variation and hardness are recorded against the batch, then part numbers and labels are matched before loading.

Wholesale Brake Discs Purchasing Guide
From your list to your price in under 36 hours
Not a form that disappears. A quotation with real numbers against your own part numbers.
01
Send Your Parts List
OEM numbers, VIN numbers or the references already in your system, with the quantity for each. If you already know which lines you want coated, say so — otherwise we quote both.
02
We Check the Dimensions, Not Just the Number
Outer diameter, thickness, overall height, bolt pattern and centre bore are verified against the application. A disc that looks correct but runs two millimetres thick is the most common way a shipment turns into dead stock.
03
You Get Pricing, Weight and a Shipping Date
Unit price per reference and per finish, gross weight and container volume, and a realistic shipping date. Discs are heavy, so the weight column is what tells you your actual landed cost.
Pricing Is Based on Your Actual Purchasing List
Final pricing is quoted according to confirmed part numbers, quantities, friction material and packaging requirements rather than a fixed website price.
Purchasing Details
| Commercial Term / Item | Details & Policy |
|---|---|
| Minimum Order Quantity | Our minimum is 100 pieces per reference. A single order can combine many different part numbers, so you do not need to reach the minimum on every line. |
| Finish Selection | Plain and coated discs are priced separately. Unless you specify, we quote both against the same list, so you can see exactly what the coating adds per reference before deciding how to position it. |
| Weight & Container Loading | Gross weight per carton and total volume are confirmed with the quotation. On mixed orders we plan the loading so the container reaches its weight limit and its volume limit together, instead of shipping air. |
| Packing & Corrosion Protection | Discs are packed against humidity for the sea journey, not only for shelf appearance — sealed inner packing on plain discs, and cartons specified for the weight rather than carried over from lighter parts. |
| Discs and Pads Together | Most workshops replace both at the same time. Discs and pads can be quoted as matched axle sets and consolidated into one shipment, which normally costs less in freight than ordering them separately. |
| Payment Terms | Standard terms are a 50% advance deposit, with the remaining 50% paid before delivery. T/T wire transfer, Western Union, PayPal and XTransfer accepted. |
| Sample Policy | Samples are free for fitment and quality evaluation before a bulk order, but the courier cost is carried by the customer. Worth knowing that discs are heavy, so air courier on a large sample set is not cheap — tell us your priority references and we keep the sample set small. |

FAQ
What is your minimum order quantity for brake discs?
Our minimum is 100 pieces per reference. A single order can combine many different references, so you do not need to reach the minimum on every part number — which is what makes trial orders and broad restocking workable.
I only have OEM numbers — can you still quote?
Yes. Send the OEM numbers, the aftermarket references you already use, or the VIN, and we identify the corresponding discs and quote against them. Matching by photograph or by eye is where fitment mistakes come from, so we work from numbers.
Are your brake discs ECE R90 approved?
Yes. UN Regulation No. 90 covers replacement brake discs as well as linings, and approval is required to sell replacement discs legally in the EU and UK. We supply the approval number and the certificate before you order, so your compliance team can verify it in advance.
Do you provide samples before a bulk order?
Yes. Samples are available for fitment and quality evaluation before a bulk order. Samples themselves are free; the courier cost is carried by the customer.
How long does delivery take?
Fast-moving references held in stock ship in 12–18 days. Made-to-order references and mixed-reference orders run 25–35 days. Send your parts list and we mark it line by line, so you know which items are stock and which are scheduled before you commit.
