Applicable Scenarios

It is installed at the rear axle of XCMG ZL50G and ZL50GL wheel loader, between rear axle swing frame and frame brake oil circuit, widely used in quarry, aggregate yard and earthwork construction sites.

▪ OEM length, fitting angle and thread specification match original parts for direct installation without forced bending
▪ Double steel wire braid reinforcement provides high pressure resistance and prevents hose bulging
▪ Inner and outer rubber resists brake fluid corrosion and hydrolysis to slow hardening and cracking
▪ Reliable crimping ensures tight connection between wire and fitting to avoid end leakage and separation
▪ Moderate flexibility accommodates rear axle swing and prevents excessive swinging and abrasion
▪ Wear-resistant outer rubber resists gravel impact and mud contamination for longer service life
▪ Compatible with booster pump, brake controller, pipe clamps and brake calipers of the same model
▪ Factory pulse pressure test screens defective hoses for reliable rear axle braking safety

FAQ 

Q：Can the hose with minor surface cracks keep working?
A：It is not recommended. Cracks will spread to steel wires, causing wire rust, burst and sudden brake failure. Replace it immediately.

Q：What inspection is required after hose installation?
A：Fill brake fluid, bleed air, test brake repeatedly and check hose and fittings for oil leakage.

Q：What causes hose bulging?
A：Bulging means internal steel wire layer is broken. It is a dangerous fault and must be replaced.

Q：Can bent steel pipe replace brake hose?
A：No. Rigid pipe cannot absorb swing displacement and will fatigue fracture quickly.

Q：How to store spare brake hose?
A：Store flat in dark and dry place, avoid heavy bending and protect threads from impact.

Q：How often to inspect brake hose?
A：Visual pre-shift inspection is required for mine working sites, check cracks and leakage at fitting root.

Q：Can I reverse the hose for installation?
A：Follow original assembly angle. Improper angle causes twisting and accelerated wear.
