Blanking Plug 1 Hole Ø 11 Disc Centre Line Alternative Outlines Side Mounting Plate Hole Details 2 tapped or through holes in side Mounting Plate to suit M8 Bolts 120 Minimum Disc Diameter 12 Centre Mounting Plate Hole Details Performance Data Maximum Braking Force = 2kN @ 20 bar air or oil pressure. Braking Force is defined as the Tangential Force acting at the Effective Disc Radius. Braking Torque (Nm) = Braking Force (N) x Effective Disc Radius (m) where Effective Disc Radius (m) = Actual Disc Radius (m) - 0.019. 20 Disc Diameter 150 Maximum Pressure 20 bar 1Nm = 0·738 lbf-ft 1 bar = 14·5 psi Braking Torque The ratings shown on the above graph are based on fully bedded-in pads. Technical Data Weight - 0.75kg (excluding mounting bolts) Pad dimensions - 35 x 50 x 8mm thick (when new) Pad friction coefficient - μ = 0.4 (asbestos free material) Pad wear allowance - 4mm Total pad area - 34cm2 Hydraulic fluid (mineral) - Shell Tellus 37, Castol Hyspin AWS 32 or equivalent Initial Oil filling varies from 2ml (new) to 12ml when pards are fully worn Oil displacement per 1mm stroke is 3ml per two caliper halves Centre Spacer same thickness as Disc Transfer Tube

DB3028 Disc Brake Caliper - Type T2 Air Or Hydraulically Applied - 2

General Description The Twiflex Type T2 disc brake unit is a split caliper design and is adaptable for use on a wide range of disc sizes, varying in thickness from 5mm and over, and in diameter from 120mm and above. The caliper will normally be mounted on a central mounting plate of the same thickness as the disc; the mounting plate is sandwiched between the caliper halves which are clamped to it by two cap screws M8 grade 12.9, tightened to 23Nm (17 lbf-ft) torque. Alternatively, the caliper may be secured to a side mounting plate, in which case a spacer of the same thicknesses as the...
