braking questions
Miks15 - 20/5/09 at 09:29 AM

On the sierra master cylinder which outlet goes to where?

Does the single one in the middle go to the back brakes then plit with a t piece? and then the two on the end of the MC go to the fronts?

Also how close can the brake lines and electrics be to the prop?

Thanks

Yes... the two front ones go to the front and the single rear one connects to the rear of the car via a T piece..

Make sure the brake lines are far enough away from, and protected from the prop so that if the prop fails or comes loose it can NEVER damage the brake pipes....

I ran my copper pipe down a piece of PVC conduit inside the tunnel tucked up in the corner where the prop could never reach

Ok well ill have to see how high i can get it in the tunnel, that will be the safest place of it i think, ill see what i can do

Imagining a situation where the prop fails enough to come away from its standard position and reach the surrounding tunnel chassis members where the brake lines are mounted with enough energy to destroy the brake lines (i.e. spinning at 6000rpm) - firstly is PVC conduit going to make a huge difference and secondly are you going to be physically capable of using the brakes?

Its only going to remove your left leg as it flails round youll still have your right one to hit the brakes

if that situation ever happened, you should still have the use of the front brakes, by the way the master cylinder works, but best to put the line somewhere where it won't get damaged.

mine run down the right hand side of the driver seat

cheers guys,

also does it matter where the pressure switch goes? or can it just go in any one of the 3 lines?

I would assume you need to connect it on the front ones as the pressure is bigger so it would trigger the pressure switch faster.

Nothing like a bit of optimism.....and that was nothing like a bit of optimism

have the switch hanging down as that will prevent air in the switch housing
