Overview & Operating Principle
▲
The SUPPORT BRAKE CALIPER is a safety-critical component of the vehicle braking system. It must provide consistent, fade-resistant friction performance across a wide range of temperatures and operating conditions. Brake components in this category are supplied to OEM-equivalent dimensional and material standards and are validated against OEM cross-reference data for direct fitment without modification.
Brake parts must be replaced as axle sets (both sides simultaneously) to ensure balanced braking force and to prevent vehicle pull under heavy braking. Never mix new and worn friction material on the same axle.
All products in this category are manufactured under quality management systems and are subject to dimensional inspection before dispatch. Confirm vehicle make, model, engine, and year of manufacture before ordering to ensure the correct variant is selected.
Symptoms & Diagnostics
▲
Squealing, grinding, or scraping noise during braking — indicates worn friction material contacting the disc or drum surface.
Vehicle pulling to one side during braking — caused by uneven friction material wear or a seized caliper on one side of the axle.
Increased brake pedal travel or spongy pedal feel — may indicate worn pads allowing excessive caliper piston travel.
Vibration or pulsation through the brake pedal or steering wheel during braking — caused by disc thickness variation or runout.
Brake warning lamp illuminated — triggered by brake pad wear sensor reaching minimum thickness threshold.
Visible wear indicator grooves on disc surface below minimum thickness specification.

Installation Tips
▲
- Verify the correct part before beginning. Check vehicle VIN, brake caliper type (single or multi-piston), and disc diameter against the product specification. Brake components are not interchangeable between axle positions on many vehicles.
- Work on one side at a time so the opposite side can be used as a reference for reassembly.
- Clean the caliper carrier and slide pins thoroughly. Apply fresh caliper grease to slide pins and contact surfaces. Seized slide pins are a primary cause of premature brake pad wear.
- Compress the caliper piston using the correct tool. Wind-back pistons (rear calipers with integrated handbrake) require a rotation tool, not a simple press. Forcing a wind-back piston will damage it.
- Torque all fasteners to OEM specification. Caliper bolts are safety-critical — use a calibrated torque wrench and apply thread-locking compound where specified by the OEM.
- Bed-in new friction material following OEM procedure — typically a series of moderate stops from progressively higher speeds to transfer a thin, even layer of friction material onto the disc surface.
Tools: torque wrench, caliper wind-back tool, brake cleaner, caliper grease, OBD-II scanner (to clear brake sensor codes).
Frequently Asked Questions
▲
Should brake components be replaced as a pair (both sides)?
Yes. Always replace brake pads and discs as a complete axle set (both left and right). Mixing new and worn components on the same axle creates a braking imbalance that can cause the vehicle to pull dangerously under emergency braking.
What is the minimum disc thickness?
Minimum disc thickness is specified by the OEM and is typically stamped or cast into the disc hub. The individual product page lists the nominal thickness and minimum wear limit. Discs below minimum thickness must be replaced, not resurfaced.
How does the OEM-equivalent aftermarket unit compare to the genuine OEM part?
OEM-equivalent grade units in this catalogue are manufactured to replicate the current OEM design geometry and material specification. Quality is verified against OEM cross-reference data. When ordering in bulk, confirm with our team that the specification matches the latest OEM revision for your application.
Is white-label or custom packaging available for wholesale orders?
Yes. ok.parts works directly with the manufacturing facility and can accommodate neutral white-label packaging or fully branded packaging with your company logo, part numbers, and barcode. Minimum order quantities and lead times for custom packaging may differ from standard stock. Contact the team via the inquiry form to discuss your specific requirements.
