Series 1000 and 1500 19 . BRAKE ADJUSTMENT : CVT 19.8 . CVT - driven transaxles use a self locking nut on the brake adjustment . See Figure 19.8 . 19.1 . On CVT - driven lawn and garden tractors , most of the braking force is generated within the tran - saxle : when the drive pedal is released , the drive ratio changes , slowing the tractor . The brake brings the tractor to a complete stop , and func - tions as a parking brake . 19.2 . When properly adjusted , the brake should do two things : it should stop and hold the tractor Lock nut when applied , and it should not drag when released . 19.3 . To check that the brakes hold the tractor : â¢ Place the gear selector in Neutral . â¢ Set the parking brake . â¢ Attempt to push the tractor . â¢ The wheels should skid without rotating . Figure 19.8 â¢ If the brakes do not hold the tractor , the brake 19.9 . Insert a . 013 â feeler gauge between the brake needs to be adjusted or repaired . rotor and the outer brake pad . There should be slight drag on the feeler gauge . 19.4 . To check that the brakes do not drag : 19.10 . If the feeler gauge is too loose , or will not go in , â¢ Place the gear selector in Neutral . brake caliper adjustment is necessary . â¢ Release the parking brake . 19.11 . A 1 / 2 â wrench will turn the adjustment nut . â¢ Attempt to push the tractor - it should move with See Figure 19.11 . less than 20 lbs . of force . More force indicates drag . â¢ If the brakes drag , they need to be adjusted or repaired . 19.5 . There is no linkage adjustment . All adjustment is done at the brake caliper . 19.6 . To reach the brake caliper , lift and safely support the right rear corner of the tractor . 19.7 . Remove the right rear wheel of the tractor using a 3 / 4 â socket . Figure 19.11 19.12 .

Series 1000 and 1500 19.13 . Check the movement of the brake arm : 19.17 . Remove the caliper from the transaxle . The brake actuator arm can now be unhooked from â¢ The brake arm should move forward as the the spring that connects it to the linkage . See brake is applied . Figure 19.17 . â¢ The return spring should draw the brake arm back against the spacer when the brakes are released . 19.14 . Visually check the thickness of the brake pads : they are visible within the caliper . 19.15 . Check the brake rotor : Caliper â¢ Confirm that the brake rotor floats on the splined shaft by sliding it in and out with light finger pres - sure . â¢ If it binds on the shaft it may cause brake drag and reduced holding performance . â¢ A rotor that has been dragging will frequently be discolored by the heat ( blue ) . 19.16 . If the brakes are dragging or worn , or if the rotor Figure 19.17 needs to be removed from the shaft , remove the two bolts that hold the caliper to the transaxle 19.18 . The rotor should slip - off of the splined shaft , pro - using a 3 / 8 â wrench . See Figure 19.16 . viding access to the fixed brake pad .

SERVICING THE BRAKE PEDAL SHAFT BUSH - the ends of the two pins ride in the peak of the INGS : crease : See Figure 19.19 . â¢ If there is insufficient travel in the linkage to fully apply the brakes , a simple visual inspection should identify the cause . 20.1 . Confirm that the brake pedal is firmly attached to the pedal shaft . See Figure 20.1 .

On assembly , apply a small amount of dry graphite lubricant to the pins and the spots on the brake arm that they contact . Do not allow any lubricant to get on the brake pad . 19.23 . Install the brake caliper , tightening the two nuts to 7 to 10 ft . - lbs . , then check and adjust the pad - to - rotor clearance . 19.24 .

After any brake service is performed , test the brakes as described in steps 24.2 through 24.4 , then test - drive the tractor in a safe area that is free of hazards , obstacles , and by - standers before returning the tractor to service . 32
