Question Wilwood calipers road legal in QLD?

Are Wilwood calipers legal in QLD ?
What I really need to know is do they have dust boots over the pistons so they can pass rego inspection?
I've found some on Ebay at the right price, but obviously don't want to spend the $'s if I can't fit them for inspection !

Prob best to ask your engineer about that one. I believe the RCR cars have Wilwood calipers..

Wilwoods don't have dust seals. However quite a few have got cars registered with them on. I think a lot of it comes down to the engineer not knowing about the lack of dust seals or the calipers being labeled as something else.

Cheers

Dust seals are not a requirement of the ADR's.

But the caliper needs to have a reasonable service life for it's use. The Wilwoods have stainless pistons and very well designed internal seals.

There are also AP's that have been approved for road use here that also do not have dust seals. Even ones fitted a while back by HSV to their vehicles.

Hi Paul
What it means is as the brake pads wear out the caliper pistons move further out. The problem is that there is nothing to protect the piston from dirt / corrosion / damage so when you put new pads in and push the pistons back the seal may get damaged or crap may just get under the seal and cause a failure.

Wilwood brake calipers are not road legal and state that on the box they come in. I have seen many cars regoed with them but like Mike says it's because the Engineer did not know or notice they have this problem.

I think Wilwood is a good brake caliper but not Road legal in Australia.

My understanding is that they're well made, reasonably priced, fabulously effective (I loved them on my car), but they are not legal because they aren't ADR approved. Never mind the design, a product can meet ADR specifications but if
that actual part number doesn't have ADR approval, it's not legal.

I must be getting old and boring, but lately I've started wondering about what would happen if the braking system of ICVs was scrutinised in the event of any type of accident/insurance claim. Scary to consider the implications...

When changing pads on any caliper without external dust seals you must use a brake cleaner to clear the exposed surfaces before retracting the pistons. This is part of the standard service technique for Wilwood etc. The pistons on these type of calipers are usually stainless and the seals are also of a higher quality as they only run a single seal.

There are production vehicles without dust seals on the calipers.

I expect Wilwood state they are not for road use purely for litigation reasons.

RCR have not yet committed to any particular caliper brand in Australia. We have been investigating and testing a variety of brands to come up with the best solution for Australian road/track conditons.

Hopefully you can get them accepted and approved as it will free up a good brake caliper for everyone to use and know in the event of an accident they will have no worries.

An Insurance company would pick this one up in a wink of an eye...anything to void the claim...Talk to the insurer. They are the REAL rule makers.

Dust seals are not a requirement for brake calipers as far as the ADRs are concerned. Dust seals are not even mentioned in the ADRs. Plenty of production cars in Australia have brakes that do not have dust seals.

But you will have more trouble getting a caliper like these passed here in Australia. Mainy because of misinformation as you can see by this thread.

We've certainly been happy with the performance of the better Wilwood calipers like Billet 6 piston.

But we have lots of options when it comes to brakes, so I doubt we will end up running with Wilwood in Australia.

Best advice was the first piece, contact your engineer about them.

I think that the tread on the caliper where the flexible line attaches is an NTP thread. I think that is not legal but easily corrected, just pull them appart and tap them with the correct thread.
