Wildwood Brake caliper brackets.

[yodagirl49]

Does anyone produce a front caliper bracket that will allow me to mount Wildwood calipers
to a XR4ti ?????
Thanks

front? Rear? which caliper? what diameter rotor? what thickness rotor?
To answer some of the unasked questions the answers are yes. yes, yes, maybe, yeah. probably and maybe..


Now we just need some questions to match the answers.

I emailed you a second time and never received a reply. Thought you might of fainted that I sent a human email lol

I made my own for the dynalite calipers with the Focus SVT front rotor (~12"x 1.1")

what rims do you have on there? I noticed you said they were 17x7.50, how do they fit with the extra width? Clearance wise

[James Wieler]

They are made by Binno model B-970, 4x108, 40mm offset, hubcentric and they fit perfectly. They were listed for the Sierra on their web site so I figured they would have to fit. However I have front coilovers so that might make a difference, I never tried them with regular struts.
I had to roll the front fenders just a smidge (I really mean just a smidge).

there might be some available

those are the rears. i have the fronts as well, but they arent on yet.

What do you use for a parking brake?

Same as what Ford used when they used this kind of brake set up.


Do it right and it fits under that consol/armrest thing...

Works gooooooood.

To piggyback off of John's reply, you must cut out the cassette holder. I'm planning to make a flat piece with cup holders in it. I have the hydraulic handbrake BTW, if that wasn't obvious.

John V,
Can you provide some details? That looks like a Wilwood, but what bore diameter? Where did you mount the remote reservoir and is the outlet line just a "Tee" fitting spliced into the rear line? If so then when you step on the brake pedal pressure would be fed to both the rear calipers and that parking brake master. I assume that's OK right? Does that compromise the pressure going to the rear calipers?

This is a great idea as it will allow the rear caliper to be mounted on the leading side of the wheel and out of the way of rear coil-overs.

What rear caliper works with this? A Wilwood I assume? What bore size?
thanks
James

I dont yet have a handbrake plumbed into mine.
the main master cylinder just feeds into the reservoir input on the handbrake master cylinder, with the output continuing on to the rear wheels. when the handbrake is not engaged, brake fluid flows freely through it.
I dont remember on bore size for the handbrake master cylinger, i want to say 3/4" or 5/8"...

[James Wieler]

Ahh, that's interesting. I didn't realize that pressure would go right through the parking master. Is it supposed to work that way?

Now that we don't need cables what are the suggestions for a decent rear caliper? I know John is using fixed 4 piston but that's probably over kill right? Even though they are a smallish bore diameter.

What do people think? Is there a fairly cheap 2 piston option available?

I like where this is going

Yes. As the brake pads wear, the piston has to move closer to compensate or else you lose brake response waiting for the piston to move enough to take up the distance that used to be pad. When you completely lift off the brakes, there is a port that will be exposed, opening the system to the reservoir. So when you are off the brakes, it's an open system. For this application it simply allows the pressure to flow through the master cylinder.

Besides going with a used 2-piston caliper, you will be spending a small amount more for a 4 piston. John chose the 4 piston caliper to match the 100mm long pad and the correct caliper volume (with the 1.25" pistons, is almost identical in area to the Scorpio/Sierra/Cosworth 43mm) that Ford used on their race cars. It just happens to be the common "Dyna" series from Wilwood. It's also common between multiple companies. For this to work properly, you need to use front calipers with properly sized pads and pistons.

John has a bracket that uses a 3.5" mount dynapro calipers. Bolts onto the XR bearing carrier and uses 11.75" 2-piece rotors (rotors available for $30 a piece). Starting price is not cheap, but everything else is.

If you are not in a hurry, I am working on brackets that use a much more common caliper with SVT focus rear rotors.

OK, I understand what you mean about more fluid needed to move into the line to take up the space as the pad wears. But can you describe the open port thing? I want to make sure I understand that because I called Wilwood about this specific point and they said it is not recommended to have pressure go into that master through the inlet line. However, who knows who I talked to.

OK, I already have Wilwood Forged Dynalite front calipers (1.75" pistons), I think John had mentioned he uses 1.625" pistons so I'm a little larger up front. These use an SVT Focus front rotor (~12" dia.)
