The brake linings are bonded to theshoes in production, but the shoes are drilled toenable replacement linings to be riveted to the shoesshould they be required in brakes are operated independently by twopedals on the right-hand side of the tractor througha suitable linkage. The left-hand brake pedal is,however, fitted with a locking pin which can beengaged with the right-hand pedal so that the brakeswill operate together. This pedal lock should alwaysbe engaged when the tractor is used on fast 1 FORDSON DEXTASECTION 1 For parking purposes the brakes may be locked on by a pawl on the right-hand brake camshaftwhich can be engaged, by means of a latch, with afixed sector on the transmission housing ( ).

Release the parking latch and jack up eachwheel in turn to Slide back the plate covering the adjusteraperture at the rear of the brake plate and, using ascrewdriver, turn the notched adjuster wheel towardsthe rear of the tractor to expand the brake shoe inthe drums (see Fig.)

Continue until a definite drag is felt when thewheel is turned, then slacken back the adjuster untilthe wheel is just free to Repeat at the opposite wheel an finally roadtest the tractor to check brake the brakes for signs of pulling to one side orover-heating due to the shoes dragging , andreadjust if necessary. Close the adjuster aperturecover BRAKE ADJUSTMENTWhen new brake shoes are fitted or when theadjustable steady posts have been disturbed, it isnecessary to carry out the following major adjustmenton each With the rear end of the tractor completelyjack up and the wheels removed, disconnect thebrake rods from the pedal at their front ends andensure that the brake camshafts are free to To obtain an approximate setting for the adjust-able steady posts.
