Short answer: a commercial brake caliper RFQ should identify the exact reference, vehicle or brake application, left/right position, mounting structure, actuator relationship and included carrier, pads and hardware. It should also state sample approval evidence, quantity, destination and packaging. A front photo and a generic term such as “loaded caliper” are not enough for a comparable quotation.
This checklist is for importers, truck-parts distributors, repair chains and catalog teams comparing commercial brake caliper suppliers or manufacturers. Send the same dataset to every supplier before comparing price.
Commercial brake caliper RFQ data table
| RFQ field | What to provide | Why it matters |
|---|---|---|
| Reference | OE, aftermarket, buyer or fleet number with suffix/revision | Prevents matching only by appearance |
| Application | Truck/bus, axle or brake application and destination market | Separates similar references and market requirements |
| Side | Left hand or right hand in installed position | Caliper orientation and mounting may differ |
| Supply scope | Caliper-only, semi-loaded, loaded, carrier/bracket, pads, actuator and hardware included/excluded | Makes quotations commercially comparable |
| Mounting | Rear view, critical dimensions, fixing points and carrier relationship | Distinguishes similar front-body shapes |
| Actuator/mechanism | Actuator-side view and required relationship to the caliper | Confirms the intended air-disc assembly configuration |
| Finish | Approved finish/color and corrosion-protection requirement | Affects process, approval and cost |
| Approval evidence | Drawing/inspection points, sample, fitment and required test evidence | Defines acceptance before bulk production |
| Commercial data | Trial quantity, annual forecast, destination and Incoterm | Allows MOQ, lead-time and freight basis |
| Packaging | Neutral/private-label files, barcode, inner protection, carton and pallet specification | Prevents late packaging changes |
Define loaded and semi-loaded scope
Loaded and semi-loaded terminology varies between suppliers and markets. Do not assume that pads, carrier/bracket, pins, springs, actuator or installation hardware are included. Attach a component list or marked layout and require the supplier to return an itemized bill of supply with the quotation.
Eight-photo minimum evidence set
- Complete front-body view.
- Complete rear mounting view.
- Actuator-side profile.
- Opposite-side profile.
- Carrier/bracket and fixing-point close-up.
- Nameplate, casting and stamped-reference close-ups.
- Critical measurement photos with reference points visible.
- All included components laid out together.
For camera position, filenames and common photo errors, use the commercial brake caliper photo evidence guide.
Supplier qualification evidence
- Cross-reference or proposed drawing tied to the quoted SKU.
- Dimensional or inspection report for the approved sample.
- Component list for the quoted caliper configuration.
- Applicable material, finish or test evidence required by the buyer.
- Lot identification and repeat-order traceability method.
- Written change-control process for material, tooling or sub-supplier changes.
- Approved packaging and label proof.
Sample-first approval sequence
- Supplier reviews the SKU list and identifies missing data.
- Buyer and supplier freeze the proposed reference, side and assembly scope.
- Supplier returns the sample, inspection evidence and packaging proposal.
- Buyer completes dimensional, mounting, fitment and required performance validation.
- Both parties record the approved reference/revision before the production order.
A platform name, photo or visual comparison is not final fitment approval for a safety-critical brake component.
Common RFQ rejection or delay reasons
- No complete part number or readable casting/nameplate reference.
- Only one front photo and no rear mounting view.
- Left/right position not recorded before sample removal.
- “Loaded” requested without an included-component list.
- System XL or another platform name used as the only identifier.
- Multiple SKUs mixed together without separate photos and filenames.
- Private-label packaging requested without quantity or artwork requirements.
What should buyers send Meklov?
Send a prioritized SKU list, the ten RFQ fields above and the eight-photo set. Meklov will review whether a matching truck or bus brake caliper supply option can be quoted and identify missing information before sample discussion.
