Tank 300 GWM Great Wall Auto Parts Rear Brake Caliper Assembly 3502103XKM01A 3502104XKM01A

This rear floating brake caliper integrates hydraulic braking structure and built-in EPB electronic parking motor, manufactured per original vehicle brake system drawings and fully compatible with all GWM Tank 300 off-road SUVs. It converts brake fluid hydraulic pressure into clamping force to squeeze friction pads against brake disc, with independent electronic parking actuator for stable hill hold and static parking lock function.
Caliper body adopts high-strength cast aluminum alloy with fine precision machining, inner cylinder wall finish Ra0.8μm to reduce seal abrasion. Stainless steel piston equipped with double-layer fluorine rubber dust & oil seal, resisting mud, rain and high-temperature brake fluid erosion; sliding guide pins coated with long-life lithium grease to ensure flexible caliper floating without stuck jitter during braking. Built-in EPB drive motor matches original CAN bus signal protocol, no fault code alarm after installation.
All mounting bracket hole spacing, brake pipe thread and pad limiting slots strictly follow OEM dimensional standards, bolt-on installation without modifying rear suspension or brake pipeline. Every caliper passes high-pressure hydraulic sealing test, 600℃ thermal cycle aging, sliding reciprocating durability and EPB signal calibration before shipment, ideal replacement for calipers with seized piston, oil leakage, abnormal parking failure and uneven pad wear.

All trim levels of GWM Tank 300 off-road SUV

1. 1:1 OEM casting & machining, fully match rear brake disc and friction pads without eccentric abrasion
2. Integrated original-spec EPB motor, stable parking lock performance on steep slopes without slipping risk
3. Ultra-smooth cylinder inner wall + dual sealing system, effectively prevent brake fluid leakage under long off-road heavy braking
4. Pre-lubricated coated guide pins maintain flexible floating movement, eliminate steering pull and brake vibration noise
5. Complete hydraulic, thermal and electronic durability testing, reliable braking safety for full-load cross-country driving
