Right I'm running water cooled ap front brakes on my space frame mk2 escort, these where on the car when I brought it but the water cooling was not used.any people use water cooled brakes on there cars? How is the water side piped in?do you go into the cars normal radiator? Or use a separate radiator,pump,header tank etc.thanks inadvance guys

 

Don't water cooled brakes just spray a mist onto the brakes, so it's not a closed system with a radiator like engine cooling. I've always assumed it will just be a reservoir and a pump. Hands up though, I do know nothing about these set ups so could be completey wrong. It's just what I assumed from watching truck racing on the telly a few years back.

 

Use a charge cooler setup? Keep it seperate from the engine coolant I would have thought

 

Cheers fellas,be handy to hear from someone running these type of brakes tho tbh.car goes for cooler and rad etc to spec-r soon and if it needs a stand only system I will get it made while there.thanks for your replys tho.
Anyone else shed any light please?

 

Speak to Mike Rainbird mate,
He has watercooled aps but he will probably tell you theres no point running water to them

 

i know that race trucks use them. But the just spray a mist of water on the brakes or something like that. I do know its not a closed system. For them anyway

found this. Google

 

but half way down the thread the guy gets the piss ripped out of him because he's apparently put the discs on the wrong way around and the calipers aren't titanium and the pads need to be seeing 1000 degrees to work at their optimum

 

cheers fellas,anyone else any thoughts please

 

if there like my old ones the water take off is at the rear of caliper

 

Learn to read dojj. No one even says those first 2 things, and the 3rd thing, he gets shot down by the guy who was responsable for the water cooling/brakes on those cars.

 

ford motorsport used watercooled 4 pot ap's on the 4dr sierra 4x4's man

 

On the group a cars they used a headlamp washer pump that was activated via the brake light switch so the spray activated every time you press the brake,

This was not a closed system, just fed from a water tank on the grp a cars and from the iss tank on the wr cars (if they run wc)

The Grp a manual states:

"Water cooling is recommended for the front brake calipers on tarmac and rear brake calipers on gravel"

"The caliper pipes are made from steel 'bundy' tube with the end brazed and a small spray hole drilled"

Hope that helps you a bit,

Thanks

I used to run some on a Manta400 rally car, It was a closed loop system, the pump(bespoke & expensive) was switched from inside the car and only utilised when conditions required. To help keep the costs down we used a rad from a Yamaha DT175 enduro type bike, which came from a bike breakers.

 

How did you run a closed loop system? Unless all it did was to cool the calipers?

If it was like truck racing water cooler brakes then as said above, its just a mist for the discs to cool.

 

It just cooled the calipers.

 

heres another thread
https://passionford.com/forum/genera...he-brakes.html

 

The calipers pictured in that thread are the same as the ones I ran.

 

Nice one

Did it make much difference?

 

ever seen a powerfull hefty rally car finish a stage with the brakes on fire man ? it made a huge difference but then so did 6pots then 8 pots

 

A huge difference, we got the calipers at the right money too, so it was a real result
