Front Wilwood Brakes

[racephotoman]

Installed suspension according to FFR manual (two holes for the brake caliper mount is facing top front and arm to attached to the steering later faces toward the rear of the car). Started to install the Wilwood front brakes and their instruction sheet show the front suspension installation (spindle) in their diagram backward from what I have. Again, the way my front suspension is installed (unless it's backward), the bracket that you would be attaching to mount the caliper on the spindle is facing toward the top and front of the spindle. Wilwood's instruction depicts this mount ing would have the calipers facing the top rear of the spindle where FFR has it to be mounted top front (again, unless I installed the spindles incorrectly). Again, my front spindles are installed to allow the wildwood caliper mounting bracket to face top front and the attached steering arm to face rear of car. Basically does it matter which way the calipers are mounted (facing) on the spindle? Any good photos of the front spindle area to make sure my is correct? And w/Wilwoods mounted?

Any help is appreciated.

Decided easier to add photo - this is my passenger right side spindle. Again, Wilwood's instructions show the two upper holes to mount the caliper bracket facing top rear - hence my concern.82013

On the 33 the spindles are switched and the calipers mount on the front side not the back side of the spindle

On the roadster, the spindles are mounted opposite of how they are marked; PS installs on DS and DS installs on PS. For the 33, they should go on the side indicated. The roadster is front-steer and the 33 is rear-steer, meaning that the steering arms face forward on the roadster and rearward on the 33.

I just completed rough mounted the calipers - please check the photos - they were both taken from the drivers (LEFT) side. While the front calipers are mounted facing front, opposite of what the Wilwood instruction said to do (of which I couldn't) and Gordon said was the way, I did mount the rears as per Wilwood instruction though - BUT now seeing the emergency brake bracket, I think it too they should be the opposite way (flipped) - This is assuming the emergency cable will pull from the vertical bracket on the caliper.

Also, If you can please look at the close up of the caliper - this was photographed from the driver's side (right) - the larger piston in the caliper is facing the rear of the car - Is this correct?

Sorry about probably very basic questions!

Because of the length of multi-piston calipers many will be configured with staggered pistons to provide a pressure differential from the leading edge to the trailing edge. This compensates for debris trapped between the pad and rotor that tends to float the trailing edge. The large pistons go to the trailing side to even out the pad wear.
