Applicable Scenarios

It is used for front axle brake circuit of XCMG ZL50G and ZL50GL wheel loader, widely applied in quarry, aggregate yard and earthwork sites. It absorbs relative displacement during steering and bumping, transfers brake pressure stably and ensures reliable braking response. It is a safety-critical brake pipeline part.

- OEM specification, thread, length and bend radius follow original drawing. Direct fit without pipe modification, saving installation time and avoiding leakage risk
- Three-layer composite structure: oil-resistant inner layer, high-tensile braid reinforcement and weather-resistant outer rubber for harsh outdoor quarry conditions
- Precision crimped fittings with uniform compression, resisting pull and twist to prevent oil seepage and separation under repeated deflection
- Good flexibility to absorb relative movement between frame and axle, preventing rigid pipe failure and stabilizing brake performance
- High safety margin via burst and pressure hold test, resistant to bulging under continuous heavy braking with responsive brake feedback
- Standardized brake component, compatible with rear brake hoses and brake assemblies of the same model for convenient maintenance stocking
- Abrasion and tear-resistant outer rubber resists gravel impact, extending service life and reducing sudden brake failure risk

FAQ 

Q：Can this front axle brake hose replace rear axle brake hose?
A：Not recommended. Length and layout are different. Improper fit causes tension and fatigue cracking, bringing serious brake safety risk.

Q：Can hose with minor surface cracks keep working?
A：Brake hose is safety-critical. Any cracking requires immediate replacement. Cracks propagate under pressure and may cause sudden hose rupture.

Q：What causes oil leakage at brake hose?
A：Common causes: rubber aging, crimp joint fatigue or twisted installation. Never twist the hose during fitting.

Q：Do we need to bleed air after replacement?
A：Yes. Air in brake circuit leads to spongy brake feel and longer stopping distance. Proper bleeding is mandatory.

Q：What to check on receiving goods?
A：Verify part number, check for bulge, crack and scratch, inspect crimp fittings and test flexibility, confirm intact threads.

Q：What is the recommended replacement cycle?
A：For harsh quarry conditions, inspect and replace every 1–2 years. Rubber degrades over time even without visible damage.
