C43 Brakes

[BenzOnline]

Hi guys!

Recently there has been something weird developing with the braking system on my 99 C43. It almost feels like air in the system but its not really that problem because when you pump the brakes it doesnt get harder.

The problem is lately as you apply brakes to come to a stop, the pedal travels half way while no braking power or action is being applied, then all of a sudden the brakes kick in and it can be sometimes quite sudden. It just doesnt feel proper and its becoming more apparent.

Could this be a brake booster, master cylinder im not sure. Fluid appears to be ok and at a good level.

THanks
