Komatsu loader brakes

[grademan1]

Does anyone know how to correct "grabby" brakes on a Komatsu loader? Our loader is a 2005 Komatsu 380.

When you say grabby, what exactly do you mean? padel all the way down before they work? or jumping about when you press them! is there any nosies when your braking?

Grabby is often a symptom of oil contamination if it persists or rust if its only the first few stops. Disc or drum? Thinking its going to be disc.

I mean when you barley touch the pedal they r grabby. this is a loader we bought new and has 800 hrs on it.

First of check the axle oil, (this will also be the oil the brake discs are immersed in) it most likely has not been changed since new!
Coming up on its first 1000hrs id say that could be your problem, it will likely have a sliver tint to it cos it is its first change, but that would be normal!

Try that and let us know if it helps!

Any noise when it's braking or is it just touchy?

sure it's not hydrostatic drive?
