Ultima Brake Master Cylinder suitable for Nissan GQ Patrol Y60 Disc Disc
Ultima JB1775 brake master cylinder suitable for the Nissan GQ Patrol Y60 with discs front and rear, built from 01/1990 to 1999: the ST, Ti and RX wagons and the coil spring cab chassis. It has a 26.99mm bore and comes with the reservoir and level sensor fitted.
If the pedal creeps to the floor at the lights with dry wheels, the seals inside the master have gone. Drum rear GQs take the 25.4mm JB1777 instead, which we also list.
