    Brake kits

    Brake kits would have to be the most talked about topic in this Brake Clinic.
    I'd like to make this thread dedicated to retail brake kit specs and images for others to reference. There is some good affordable products coming out lately and it would be good to have a single thread to view them.
    That's retail kits please!

    We (DBA) are often involved in development of the retail kits but they are not sold by DBA.

    Also if there is a moderator who can make this a sticky it would be good......
    I had my mod rights taken away...........

    This was put on an Excedy drift/show car in the USA. Normally you would run a slotted disc.

    why do you need big brakes on a drift car...its all low speed stuff and short duration?
    BTW how true is the report I have re slotted disc's and an increase in pad wear of up to 20% for a 5% increase in perf?

    Have you heard the term "Bling Bling" The brake kit on that car is just for show which appeals to the USA market. The kit itself (with a slotted rotor) has far greater potential.


    I would like to see this report. Can I get a copy or can you give me the author's name?


    Thanks for the sticky Chris...

    steve,

    can you find something to fit on the front of a combo van (SB barina)

    there are kits in europe that put a 288 x24 mm rotor on the fronts and use vectra V6 brakes. just need the rotor (4x100 is the pcd.) or if I can get a 308 x24 under it?

    (16" wheel and I cant change them.)

    DBA 825 is the Vectra front disc you mentioned but we don't have any un-drilled.
    DBA 2500 is coming up for production which could be made un-drilled. It's 300 x 25mm
    Or I am working on the ST170 Ford Focus 300mm x 24mm which looks to be close to what you want.

    DBA 5000 flat disc only would suit if you need to make a hat for a custom rotor offset/fitting.

    Depends on your time frame I suppose.

    Vectra (Opal) caliper takes a 25mm thick rotor.

    http://www.hoppers.com.au

    TORANA’S – LC to UC and HR stubs

    Included in Kit:

    * Pair 290 mm Disc Rotors and Twin Piston Calipers
    * Set Semi – Metallic Brake Pads
    * Caliper mount kit with Bolts
    * Pair Conversion hubs made from K1045 Billet steel fitted with bearing
    cups and Genuine Holden wheel studs
    * Pair custom Brake Hoses and copper washers
    * Full Fitting Instructions

    Priced from $1100 Smooth, $1200 Slotted, $1250 Drilled and Slotted.
    Some further I've found out about this kit (specifically the HR based kit):

    * Uses AU2 calipers(PBR) and rotors(DBA).
    * Bolts to a HR disc brake stub axle using an adaptor plate, two spacers (ie one per caliper bolt) then fit between the caliper and the adaptor to locate it in the correct position.
    * Increases wheel track by 10mm
    * Kit can be set up for any stud pattern, the rotors are purchased as blanks and drilled to suit.
    * Hoppers have had a Vic engineer write a report on the kit.

    dbasteve, I'm interested in whether you know of any other quality brake kits to suit HR front ends? At the moment, Hoppers seem to be the only place that give me confidence.

    Nah!
    I don't know of anyone I would recommend. There aren't many people making good kits for old Holdens.

    dbasteve, are you able to give me any comments on what the AU2 brakes are like in general?

    I really know nothing about them, i'm assuming they are a twin piston design?

    AU 2 & 3 rotors are much better than AU1 due to the increased thickness but are still quite average for such a heavy vehicle. Hoppers use them a lot for upgrades on lighter cars which perform well.

    The caliper is a PBR twin piston sliding unit. I haven't had a lot of feedback on these which usually means they are O.K.
    Please note - It is very important to check that your current master cylinder can handle these calipers. I have heard of a few kits having a shocking low pedal because of a master cylinder that is too small.

    The setup they currently seem to be suggesting is an XA/B master with a Gemini booster.

    What would be a good upgrade for an XF Falcon? Should I start by changing the drums to factory discs?

    I'm out of my comfort zone with this old stuff..........
    Hopefully we'll both learn something with the XF.

    HR kits ..... few and far between. I mean how many are left really ?
    The market is nearly dried up on this old stuff. Its a matter of take whats available or reinvent the wheel.

    Hoppers do an XF front kit too. I haven't seen anyone else that does a good one.
    Yanks do a similar thing with Wilwood calipers as the spindle is similar to old Mustangs etc.
    For the rear I'd be grafting in a disc brake setup off the same model..... loads of those in wreckers.

    the only requirement I have is that it uses the factory vectra caliper and fits under a 16x6 wheel (ET49) from there I'm not too fussed. I'll have to read up on the 308 mm item as I'm not sure what it comes off. (thinking calibra turbo but not sure.)


    the probelm I have is : vehicle weighs 1900kg and doesn't pull up the best . its had an upgrade already with TR astra (256x24) rotors and calipers. that fixed it a bit but doesn't pull up in a hurry.

    In short I'm trying to get GT3 stopping power in this thing.

    ideas?

    Holy snappin ducks.......1900kg...is quite a load.
    I'd be looking for a disc around 7kg to handle the heat load from pulling this car up. Vectra discs are only around 5 to 5.5kg.
    It may be worth looking at the DBA 963 Skyline rotor which suits a 16" wheel. The disc is 26mm thick so you need to check the clearance in your vectra caliper. I would be putting all efforts into running as thick a rotor as possible with a 16" wheel restriction.

    Btw, speaking of stands, the DBA stand at the aftermarket show in Darling Harbour was very well presented.

    Question. There's been talk of people wanting to upgrade Astra non turbo (280mm) with the turbo ones (308mm) using the same calipers but with an extra bracket (basically same setup as it is on the turbo) but what I want to know is that for those driving non turbo cars that want to do this upgrade need to have them engineered even thought it's factory fitment? If so, how much generally do they charge?

    Thanks for the comment on the stand.

    Because you would be adding a non O.E bracket the setup needs to be inspected by an authorised Engineer. The cost can be up to $400. If the upgrade is identical to one that had been passed before then it may be much cheaper especially if the same Engineer is used.
    If you can get a few guys together and have the brackets and any other components made in one batch you may save quite a few dollars overall.
