Final answer:
To check the free play of manual slack adjusters on s-cam brakes, follow these steps: Park the vehicle and engage the parking brake. Locate the slack adjusters and measure the free play. If necessary, make adjustments within the acceptable range.
Step-by-step explanation:
To check the free play of manual slack adjusters on s-cam brakes, you should follow these steps:
- Step 1: Park the vehicle on a level surface and engage the parking brake.
- Step 2: Locate the slack adjusters on the brake system. They are typically found at the end of the s-camshaft.
- Step 3: Measure the free play by using a slack adjuster tool or a wrench. The free play is the distance the adjuster can be moved by hand without resistance. Refer to the manufacturer's specifications for the acceptable range of free play.
- Step 4: If the free play is outside of the acceptable range, adjustments need to be made. Consult the vehicle's repair manual or a qualified technician for specific instructions on adjusting the slack adjusters.
Remember to always prioritize safety and consult appropriate resources when performing maintenance on vehicle systems.
