The BRAKE PADS are friction elements mounted in the brake caliper that clamp against the rotating brake disc under hydraulic pressure to convert the vehicle's kinetic energy into heat through controlled friction, decelerating the wheel. Each pad consists of a steel backing plate to which a friction material compound is bonded under high pressure and temperature. The friction compound formulation determines the pad's performance envelope: NAO (non-asbestos organic) compounds offer quiet operation and low disc wear at moderate temperatures; semi-metallic compounds provide higher thermal capacity and fade resistance for heavier vehicles and demanding driving conditions; and low-metallic compounds balance stopping performance with dust and noise characteristics for typical passenger car use. Most OEM-specification pads include a wear indicator — either a steel tab that contacts the disc and produces a high-pitched squeal at minimum thickness, or a wired sensor that triggers a warning light on the instrument cluster.
This unit — UAZ 31603501090 — is manufactured to OEM-equivalent specifications: backing plate dimensions and steel grade, friction compound formulation and ECE R90 certification, pad thickness at new, shim configuration, and wear indicator type are matched to the original part. Supplied as a direct replacement for standard fitment. Available wholesale from 3.54 USD, MOQ 1 pcs, production lead time 30-45 days.
Brake pads wear at a rate determined by driving style, vehicle weight, and brake balance — front pads on front-wheel-drive vehicles typically require replacement at 30,000–60,000 km while rear pads may last twice as long on the same vehicle. Minimum friction material thickness is typically 2–3 mm; replacement at or before this threshold prevents metal-to-metal contact between the backing plate and disc surface that will score the disc beyond the minimum thickness specification and require combined pad and disc replacement. Never defer pad replacement once the wear indicator activates.
- Measure disc thickness and check for scoring before fitting new pads — use a micrometer to confirm the disc is above minimum thickness at multiple points around the circumference. A scored disc with grooves deeper than 0.5–1.0 mm will destroy new pads rapidly and must be replaced or machined before the new pads are installed.
- Clean the caliper slide pins, carrier bracket abutment surfaces, and piston face with a wire brush and brake cleaner before fitting new hardware. Apply a thin film of ceramic or copper-free brake grease to the abutment surfaces and slide pin bores only — never apply any lubricant to the disc face, pad friction surface, or pad backing plate friction contact area.
- Retract the caliper piston fully using a piston wind-back tool before fitting the new, thicker pads. On rear calipers with integrated electric parking brake, the piston must be wound back clockwise using a dedicated wind-back tool — never attempt to compress a rear EPB piston with a C-clamp as this will damage the internal thread mechanism. Open the bleed nipple slightly when retracting the piston to avoid forcing old brake fluid back through the ABS modulator.
- Fit all new hardware supplied with the pad set — abutment clips, anti-rattle springs, and shims are application-specific and are included because the OEM requires them for correct pad retention and noise suppression. Reusing old hardware with new pads is a common cause of brake squeal and pad rattle complaints after service.
- Verify the electronic wear sensor connector is correctly routed and connected where fitted — the sensor wire must be routed clear of the disc and any rotating components, with sufficient slack to accommodate caliper movement during braking without pulling the connector free from the pad.
- Install the new BRAKE PADS (UAZ 31603501090) on both sides of the axle, torque all caliper bolts to OEM specification, pump the brake pedal firmly until the pedal feels solid before moving the vehicle, bed in the new pads by performing 8–10 moderate stops from 60 km/h to 10 km/h with 30-second cooling intervals between each stop, and clear any stored brake warning light codes.
