Definitive AU1 to AU2/AU3 brake upgrade thread

[auxlr8]

Is the grub screw actually needed? Wont the studs and wheel nuts locate the disc anyway? What have you guys done in regards to the dust cover? Im thinking of just completely removing it?

If you mean the stone shield, I ended up removing it.

If you mean the rubber grommet that covers the adjuster, I used BA ones (on the right in this picture.

[auxlr8]

What is the rubber grommet for? This is the first time ive heard of it

cheers

yea gotta remove the dust cover, a lot of swearing will happen as its fiddly,

The grub screw isn't really needed, but I think why they put it there is for when you adjust the park brake. You cant do with wheel on. The rotor needs to stay square. Guess you could nip up all the wheel nuts.

I put the grub screw in.

So guys I don't know if I'm doing something wrong or I have some wrong parts. I've got the lower control arm and upright assembly as one piece on my garage floor and loosely looking at how the ba carrier and caliper bolt onto the upright and it's just dosnt look like it will fit. The bottom ba bolt might but the top bolt looks to short to fit on the au 3 upright and even if it did it looks like it's too far in towards the body for it to go over the disc. Am I supposed to be using the au3 bolts on the au 3 upright with the au3 carrier and then attach the ba caliper to the au3 carrier? A little confused now, any advice on what I'm doing wrong?

Cheers

Post #30 tries to explain the lines.

I did the same with my aftermarket toe-link end tkfd. So far, they haven't failed!

The hole in the rotor for handbrake adjustment isn't covered by the wheel so a grommet seems like a good idea.

You can see it in this pic.

[auxlr8]

Thankyou, makes perfect sense now

[wobblysauce]

Silver', Do not think they're referring to the Handbrake hole but the tapered one that alines the Disk to the Hub.

[auxlr8]

I was referring to the locating hole on the disc as my understanding is that its really not needed as the studs, wheels and nuts locate the disc anyway but it was good to find out the info on the rubber grommet for the handbrake hole.

Thanks again for all the info

My 328mm rotors didn’t have any provision for the grub screw. I’d use it if it was there.

Trying to work out how I can attach pictures mate and that's a struggle atm too.

I'm using an I phone is that why I can't attach?

[auxlr8]

Struggling to upload pics from my iPhone. I'm thinking maybe the wreckers gave me the wrong lower arms and uprights maybe. On the passenger/left side with the curve of the lower control arm facing forward and stamped LH the caliper position is still facing the rear as per my current series 1 where it should now be forward as per series 3?

Cheers

[BlueBear]

Sound like the wrong upright, should definitely be mounted on the front of the axle line.

This is mine part way through the conversion, the suspension changed over, but the old caliper still hanging there - drivers side.

Cheers,

[auxlr8]

Yep, thankyou for that photo, it does appear they have given me the wrong upright and lower arm assembly. No wonder why I couldn't quite work it out. Thanks heaps. I'll go back Wednesday after cup day to get the right parts. Should my ba carriers and calipers use ba carrier bolts or should I be using au2/3 bolts?

Cheers

[JC]

These are the pics of the parts auxlr8 was supplied with:

Are they AU1 spindles with AU2/3 sway bar bits? Or could they be the spindles for premium brakes?

[auxlr8]

When I went to the wreckers I asked for au 3 lower arms with hubs and spindles, uprights and au3 sway bar and mounts. It's taken a month for them to have the time to get it all together and it now looks like they have accidentally given me au3 sway bar, mounts and links but with au 1 lower control arms and uprights.

[BlueBear]

The uprights aren't just on the wrong bottom arms are they?
Has the bottom balljoint been disconnected?
If so, just swap over the uprights and see if they look right, just that they look correct from my recollection. For example, the ABS sensor is in the correct position, they are on the front side of the series I stubs...

Cheers.

[auxlr8]

Nah it was removed as one piece with the lower arms and uprights still connected without the ball joint broken and still connected. I'm thinking they have just given me series 1 lower arms and uprights with a series 3 sway bar and mounts?

[auxlr8]

So I went to back to the wreckers today with all my parts and begin to have a crack that they gave me the wrong parts.... luckily before I opened my mouth the owner took me to the donor car.... indeed a series 3 au. An xr6 that for some reason had sseries 1 uprights on it which then led me to believe it had the premium brake combination that indeed used series 1 uprights on a series 3. Would anyone know if this premium option that used series 1 uprights were twin piston caliper and what sized discs? I've got the wreckers now looking for those original calipers in case they are twin piston and may bolt straight onto my au1 Fairmont ghia.... bit of a long shot but maybe?

Cheers

[BlueBear]

I believe they were a twin piston and an even larger disk than the BA, though I can't remember the actual size.
It should fit up, but you will need at least 17" wheels.

Cheers.

[auxlr8]

Thanks for the info mate. For them it's like looking for a needle in a haystack full of ford calipers. Anyone perhaps have a serial no or caliper model no or exact disc size I can pass onto them to help look. Would they have tickford or premium printed on them? Painted? Would seriously turn a massive job into an hours job with the same result

Cheers

Painted red.

It also saays they are 329mm disks.

Please note I have never come across these, so my info is not to be taken as gospel.
Hopefully others with experience will be able to help out.

I reckon though, that if these wrecker guys didn't remove the disks and calipers they would be long gone.

Cheers,

[auxlr8]

Thanks heaps for the help. He thinks he has them laying around so fingers crossed. You guys are like the Wikipedia of au falcon!

The factory rotor size for premium brakes is 329mm but aftermarket ones are listed as 330mm. They use C4 calipers (twin piston) and have a "TICKFORD" logo on them. The actual size of the C4's are smaller than the calipers used on BA's but not sure if the piston sizes are different or the same. The pads are bigger on the BA calipers.
I think there is a bracket that goes between the upright and caliper to allow the caliper to move out for the bigger rotor. They used a bracket for the C4 calipers that mounted at the front of the wheel on Ser 2 & 3 .

[superroo]

Yep premium brake uprights. Sought after but useless without the calipers.

Was C4 corvette calipers with the tickford symbol.
Discs were 329x25mm

Second best non brembo combination and is period correct
