Giulietta Front Wheel Cylinders - Early Giuliettas were fitted with 0.875” OD front wheel cylinders. These were upgraded to 1.0” OD to give increased braking power. We do supply 0.875”OD kits and cylinders when required . Some owners prefer to upgrade to the 1.0” OD type. Note it is essential that all cylinders are changed to the 1.0” OD for even braking.
