230SL Clutch Slave hose
« on: August 20, 2010, 23:31:58 »
Hi--

Does anyone know the working strength/burst strength of the clutch slave hose (part # 0002950335) on the 230SL?

I assume that it is the same as the brake hoses, but I also don't know the strength of those hoses.

Thanks,

Joe

Hello Joe,

The constuctionseems to be nearly the same as  brake hoses, so the pressures must be fairly high.

Would you even come close to having the same kind of pressure as you would during a normal braking sequence?
Since the clutch is being activated wouldn't the hydraulic system give up some of this pressure as lateral movement in the throw out bearing and pressure plate?

 In braking, the caliper piston moves a small amount until added pressure creates enough force to stop the rotor from turning. 
Somehow these two things seem to be different although both are using hydraulic pressure to create mechanical leverage or drag.
