Hi Hypnodoc, Sorry if you feel you have been ignored. We get flooded with hundreds of emails from all corners of the globe and we try our best to get around to them all in a timely manner. I have checked all enquiries around the dates you have mentioned and we cannot see your request. In reference to your issue, as the gold rotor is a one peice design design, made here in Sydney, there is nothing related to the rotor that can create a rattle as it is clamped securely by the wheel. This is a very popular rotor for DBA and as an OE supplier to FPV and HSV we can guarantee that our spec is true to the original equipment. The only area where a rattle could possibly develop is in the caliper where the anti-rattle clips are not fitted correctly or on the caliper mount. Not being able to hear the noise we can only make an assumption based on our knowledge of that application. I am assuming you still have the gold rotors fitted. Can to please send the details of your supplier and fitter and a bit more more detail on the noise, eg speed, pedal pressure, etc. to dbasteve@dba.com.au regards, DBAsteve

Congrats on being one of the first to get your hands on the new design. We are very pleased with what we have achieved so far. We have been working on this design for a couple of years now with extensive R&D being done with the V8 Ute category as well as a few endurance teams, the feedback we have received from the teams has been fantastic. To top this all off we presented this new design at this year’s Australian Automotive Aftermarket Expo and it took at Best New Performance Product and we also took out Manufacturer of the Year making us the most awarded aftermarket manufacture in Australia. The big plus for the street guys is there is no more lefts and rights, more bite, they are quieter than the old 6x6 design and now the slot patterns on the 5000 Series is the same as the 4000 Series so when you fit this combination the both look the same. If you want more info on these rotors visit the site below, we have also included our new launch video which shows how DBA manufacture and what sets us apart from the competition. www.clubspect3.com Regards, DBAsteve. dbasteve@dba.com.au

Hi Guys, Yes slotted rotors can be machined, they just cant be machined the same way normal discs are done. I have attached a PDF that explains it all. Regards, DBAsteve dbasteve@dba.com.au T014 - Machining Disc Rotors_0.pdf

Boost69, We would like to help you with your problem, I have sent you a message with details on how to contact us. DBAsteve,

You need to pull the rotors off and have the hubs checked for run out, this can only be performed with a dial indicator. The same process must be done with the rear, some people are unaware that rear rotors can cause brake shudder.

If you have left the car over night it may only be light surface oxide (rusty colour) which would disapear after first brake application. Some pads can put down a transfer layer during the bedding in process, this will dissapear once pads have settled in. One thing you need to understand is that slotted rotors will create a hum/vibration once heat is generated into the rotor. if the noise/vibration you felt is not there when the rotors are cool then that's all the noise is. My DBA car can get quite loud when the brakes are working hard, this is normal. In normal driving they should be very smooth and quiet.

Hey Ghosti, If you're thinking of changing calipers etc, I'd suggest picking the brains of some of our performance distributors. They'll be able to pair a suitable set of calipers to a set of DBA's 4000 or 5000 series, that'll no doubt put a smile on your face. Just checkout the 'where to buy' section on our website. All the best. DBA Steve dbasteve(at)dba.com.au

Hey Lukexr61988, Hope the 4000 series are working seamlessly for you. Just a note on bed-in procedure. 1. After installing new disc rotors &/or brake pads, perform 8 to 10 slow downs applying moderate pressure from approximately 50 – 60 kph without coming to a stop. 2. Make an additional 2 to 3 slow downs applying heavy pressure from approximately 60 - 70 kph without coming to a stop. 3. DO NOT DRAG BRAKES! 4. Check that the discs have an even surface appearance (they should be a consistent blue tinge) 4. Allow at least 15 minutes for brake system to cool down. After step 4 your new disc rotors &/or pads are ready for normal use. Be aware that the full bedding in process can take up to 300 – 500 kms depending on driving style. During this period try and avoid any high speed hard braking to a dead stop. This process essentially 'pairs' the pad to the disc and allows a good heat soak for both the pads and discs. If you need any more info, just ask. All the best. DBA Steve dbasteve(at)dba.com.au

Hey AA, Sorry for the late reply but thanks for the kind words about our product. For the BA, BF & FG XR6T we make a 4000 series OE replacement, unfortunately at the moment there isn’t enough demand for us to justify the cost of making a 5000 series. But if you want a 5000 series disc some of our performance distributors may be able to adapt another 5000 replacement disc with a custom hat to fit. As for affordable ceramics... not in the near future. Unfortunately while ceramics give outstanding braking performance, they still cost an ‘arm and a leg’ to make, they wear quicker and hence not affordable to the average performance minded car owner. Ceramics are starting to make their way onto some of the performance luxury cars, most notably with Porsche anything in their 911 range above the 911 turbo can be optioned up to a carbon/ceramic brake package with the appropriate hefty price tag. Thanks for the enthusiasm for our product. All the best. DBA Steve dbasteve(at)dba.com.au

Hi Benny Glad to see the problem was fixed, hope the cars still going well. All the best DBA Steve www.dba.com.au

Hey trevs, I can't comment on specific pads because we aren’t aligned to anyone and we need to stay independent from the brands, however look into the entry level street-track pads that have come onto the market recently. You have 3 basic options though. You can get a performance street pad, an entry level track pad or buy a set of each and change them over when you get to the track. One of the problems with running a full track pad on the road is that the pad will not reach its working temperature range and will struggle to put a transfer layer onto the disc which can cause problems with premature wear of pads & discs, noise and shudder. The flip side is that if you run a street pad on the track you risk ‘cooking’ the pad (working it beyond its temperature range) which can cause hot spots on the rotor, premature wear & cracking of the rotors. All this leading to a decrease in performance and your satisfaction with your purchases. It may just be that you need 2 sets of pads that you change over when you go to the track, so you can get the best of both worlds. If you go down this path you’ll need to bed the pads in when you change them over, so that the disc and pad work together optimally. Hope this helps, feel free to email me if you want more information. All the best. DBA Steve

Hey guys, Thought we'd pipe in and help out if we can. P4N1C, Benny, unfortunately we don’t have replacement front rotors in our range for the Ford Territory Turbo as yet. We're not really sure about the demand however, keep an eye on our new product releases for further updates All the best DBA Steve

Hi everyone, Forgive the VEERRYYY late reply but we've just been told about this thread and we wanted to make sure that we at least aswnered the original tech question at some point We've been a little removed from you guys and the forum community lately as we've been busy on a lot of other stuff but would like to make sure that questions like these get covered properly. Cro, the DBA 4000 and 5000 series rotors are designed to operate around 550°C (Orange heat paint changes) in motor sport conditions. Any extended use above 630°C (red heat paint changes) will unfortunately reduce the rotors life. The cooler the rotor can run, the longer the life expectancy. If a rotor is run at sustained temperature above the maximum continuous working temp of the brake pad then both the rotor and pad life will be drastically reduced. If you are experiencing an intermittent squeak when driving slowly it can be caused by the rotors being mounted with excessive run out. This can be caused by the hub faces not being cleaned properly or if there's play in the hub bearing(s). If you're finding that the brakes still squeal it may be worth looking at trying different brand pad options. There are a number of great option sout there. Again, apologies for the delayed reply but we're standiang by if you need any more answers. All the best DBA Steve

that's great, Main thing is you're sorted. Just let us know if you need any tech help. All the best Steve

Hi EvilDaifu, This thread is getting on a bit but I wasn't sure if you'd had a satisfactory answer yet. All the best Steve DBA
