installing Wilwood brake proportioning valve in Sydney

[youtu][/youtu]Can anybody recommend a good brake shop to install the wilwood prop valve I've purchased?

Bought it locally, so without the adapters from FM. I've checked out a local shop but they don't have any experience putting one in, and I'm not keen to pay extra in time and money for the privilege. I would've thought it was fairly straightforward for a professional shop that would have various fittings lying around. I would think it would be an hours work for the initiated + either fittings or flaring costs.

Any suggestions for a good shop in Sydney would be deeply appreciated. I dont mind driving.

It's not something you'd find on road cars due to the legal/rego issues, so would be best to target those shops specialising in motorsport applications.

Perhaps talk to Road and Race Performance at Rydalmere; Race Brakes at Wetherill Park; or better still, call Bruce Stewart at Performance Brakes and Clutches in Chipping Norton.

Just buy the fittings off FM. They made them because there is nothing on the market that works off the shelf (without using at least two parts joined together).

Flaring new pipes is a thankless task, and you wouldn't be able to revert it.

If the car is road registered (and unless you have a good relationship with your pink slip inspector), you should probably plan on "reverting" the system at least once a year.

+1 - I was pinned on mine, and my engineer has poo-pooed it without extensive (and expensive) ADR testing... which is why I am reverting back to stock rear brakes and the OEM prop valve

Thanks guys... I was somehow under the impression that it was only not legal to have them adjustable from inside the cabin; didn't know that just installing an adjustable prop valve would be not legal. I've ordered a set of adapters from FM, and hopefully will get it soon enough. It'll make installation easier and being able to revert it would be a good thing..

Thanks for all the tips about where to install them, Tony :beer:

I'll give them a bell once the adapters arrive.

Something else troubles me about the way the prop valve is installed. It says the front lines are fed directly from the cylinder and the prop valve is only used to adjust (reduce?) pressure to the rears... But the reason I want them is to _increase_ bias to the rear. Not even sure that it would work.. Maybe I should just dig up a set of NB8B rears.. should sort out the balance without all this to-and-fro..

You increase bias to the rear by reducing the amount of reduction in pressure to the rear lines. The adjustment range of the adjustable valve lets you do this.

Ah so!

thanks for that... makes sense now..

Got a shipping quote for the fittings, so might order an extra kit in case any one wants one; it doesnt change the shipping costs much. . Will do the track day in the 4th as it is (front-biased). By then the fittings would have arrived and I'll give fine tuning the balance a go.
