What Information Is Needed for a Custom Brake Seal Quotation?

To evaluate a custom brake seal quotation, HOBA needs enough information to identify the product geometry and determine whether an existing mold can be used or a new mold must be developed.

Customers do not need to prepare a complete engineering package before contacting us. However, better reference information usually leads to a faster and more accurate evaluation.

What Is the Best Information to Provide?

The ideal quotation package includes:

• An unused original physical sample
• A dimensional drawing
• A part number or reference number
• The estimated order quantity
• Available application information

Providing both a sample and drawing is recommended. The drawing shows the intended dimensions, while the sample helps confirm the actual profile, sealing lips, grooves, and molded structure.

Can I Request a Quotation with Only a Sample?

Yes. HOBA can evaluate an unused physical sample and determine whether it is suitable for reverse engineering.

An original equipment sample is preferred. A reliable aftermarket sample may also be accepted, but worn, deformed, or poorly reproduced parts may not provide dependable dimensions.

A used seal can change after installation because of pressure, heat, fluid exposure, and long-term compression. Therefore, it should not automatically be treated as the original dimensional reference.

This is one reason dimensional tolerance matters for brake rubber parts.

Is a Part Number Enough?

Customers can provide an OEM number, aftermarket number, or internal reference number.

If the number can be identified, it may help locate a corresponding product or mold. However, some reference numbers may not appear in available records.

When a part number cannot be identified, HOBA will need at least one of the following:

• Physical sample
• Product drawing
• Cross-sectional dimensions
• Clear photographs with measurements

A part number alone does not guarantee that the correct rubber component can be confirmed.

What If I Do Not Know the Exact Application?

Some customers know whether the part belongs to a brake caliper, master cylinder, wheel cylinder, or clutch hydraulic system. Others may only receive the sample from another customer.

It is acceptable if the exact application is unknown. HOBA can often recognize the general component type from its shape.

When available, customers may also provide:

• Installation position
• Piston or cylinder diameter
• Vehicle or equipment model
• Hydraulic fluid type
• Existing sealing or installation problem

These details help reduce uncertainty but are not always required for the initial review.

Why Is the Required Quantity Important?

The estimated quantity helps determine whether the project is suitable for an existing mold or requires new mold development.

For the initial quotation, customers should provide:

• Expected first order quantity
• Estimated annual demand
• Whether trial samples are required

Final requirements depend on the component dimensions, mold availability, and production conditions.

Quick Quotation Checklist

Before submitting an inquiry, prepare as many of the following items as possible:

• Unused sample
• Drawing or dimensions
• Part number
• Required quantity
• Product photographs
• Known application information
• Delivery destination

If some information is unavailable, send the available reference first. HOBA can review it and explain what else is required.

Conclusion

The fastest way to obtain an accurate custom brake rubber parts quotation is to provide an unused original sample together with a dimensional drawing and estimated quantity.

When only a sample or reference number is available, HOBA can still perform an initial evaluation and determine the next step.
