About slack adjuster repair kits
Slack adjusters connect the brake chamber pushrod to the camshaft and keep the shoe-to-drum clearance correct as linings wear.
When to replace
Excessive pushrod stroke, a brake that pulls or an adjuster that won't hold adjustment show worn internal parts.
What's in the kit
Slack adjuster kits cover worm and gear components, seals and boots for the adjusters listed. All 20 slack adjusters lines are manufactured by Pitchline Engineering in an ISO 9001 environment in Pinetown and supplied from our Pinetown branch across South Africa.
Slack Adjusters questions
What causes excessive pushrod travel on a truck brake?
Worn linings combined with a slack adjuster that is no longer adjusting correctly.
Can slack adjusters be repaired?
Yes, with the right kit, when the body is not damaged.
Does Pitchline cut gears for slack adjusters?
Pitchline has gear hobbing and shaping capacity; contact ManuMark for specific requirements.
