BRAKES HYDRAULIC SYSTEM

The JCB braking system ensures effective, fade-free braking. The self-adjusting, multi-disc arrangement is inboard mounted and is The Open Centre system uses gear pumps with a power modulation valve that automatically varies hydraulic power to match

● Twin brake pedals provide tighter turning circle and enhanced steering control on slippery ground. ● Open centre hydraulic system using simple and reliable high efficiency gear pump.
● Automatic compensation ensures ‘straight’ machine braking. ● Single pump system with priority valve to ensure metered supply to steering and main hydraulic system.
● Disc diameter: 165 mm (6.5 in). Friction area: 130502 sq.mm (202 sq. in) per brake. ● Easily used, ergonomically positioned levers give excellent control of the loader and backhoe, thus reducing operator fatigue.
● The independent parking brake is mounted on the input shaft rear axle and will hold the machine on 1:3 gradients. ● A full flow 10 micron filter ensures that oil stays free of contaminants.
It is an over-centre type, adjustable within the cab, with transmission disconnect to prevent premature brake pad wear. Park

● With the oil/air receiver only requiring an inspection every 6 years, maintenance time will be cut to a minimum.
● The compressor will only operate when the parking brake is applied. And to minimise the risk of mechanical damage,
overheat sensors will disengage the compressor drive if the oil temperature rises above normal.
