Hey Pioneer.

Don't think it's necessary to put in bigger rotors, putting some SBS HS pads (which are the 'street oriented' pads, not 'race') already made a lot of difference on mine
try some other pads first, change the master cilinder to something like an RSC , then, if that's still not enough, get some same-diameter aftermarket discs

 

Hi, I am new to this forum. I bought a 2005 GSX-R 1000 last February. I love an original motorcycle and only have a short licenseplate holder and Akrapovic demper that are non stock.

My front brakes are worn and they have to be replaced. I have got steel brakelines installed and now I am looking for some new disc's and pads.

I read that Brembo has got some oversized rotors of 320mm in stead of the stock 310mm. There are two versions, the HPK and the T drive versions.

Does anybody have the experience with the T drive disc's when riding on the street? Do this disc's rattle when not braking while you drive on a bad road?

The HPK versions have the golden heart and that is nof my first choice to place on my bike.

Another thing, I can't find anywhere which adapterkit, 5mm, will fit my standard Tokico brake calipers? Brembo has got soms spacer kits but the only information I can find is the spacers needed to install Brembo calipers.

I don't want to change the calipers but only a bigger rotor and soms brake pads with a bit more bite.

Hope someone can help me.

Best regards Ronald

Hello.... kyella as the items for sale send a text to the gmail below to buy from her.

Is the #3 post a failed attempt to quote #1, with a minor comment appended?

There are several ebay sellers of spacers but they tend to have a recess on one side and a pin on the other. Like this:

They make use of the OEM pin and probably work OK but I prefer those with a pin on both sides. Zoran sells them here, custom made to order.

Note that you're going to need caliper mounting bolts that are correspondingly longer.

The 320's will brake better but don't expect a big difference, maybe 5%. Also note that the caliper-to-wheel clearance will be smaller and removing the wheel will be much more difficult.

Both of your Brembo calipers are full floaters, which can clank a bit at very slow speeds. I haven't used either but wouldn't expect one to be worse than the other.

The OEM two piece Tokico calipers are rather crappy. The K9 Tokico monoblocs are much better, bolt on, and don't cost like the Brembos. There are several threads about them here. Unfortunately they aren't as readily available as they once were.

 

Thank you all for the reactions. I am going to search for some k9 calipers because of the reaction of BillV. Removing the front wheel is something I want to do without any issues with clearance.

Don't know if the k9 calipers are smaller but will sort that out. Maybe then a 320mm rotor can be an option. Because of the cost of the parts I want to do it right in the first go.

Hope to find some calipers

The Brembo disc's are floaters indeed. The hpk version looks like the same floating type as the stock versions. They are 5.5mm thick. Does anyone know how thick the oem disc's are?

It came with white wheels? What country?

 

I bought it like this. The wheels are painted in the same white color as the fairings. They have the same sparkle.

The dealer said it came with black wheels as standard.

 

^He's painted or otherwise changed them.

The front discs are 5.3-5.7 mm thick with 5.0 mm service limit. They are two part but not true floaters as the buttons are pressed together to effectively eliminate floating. People here used to loosen the crimp to convert them to floaters only to find that the button axis became the highest wear point, i.e. they aren't designed for that.

I've linked to this (now five years old) several times before. It's by people who race with them. One mentions 5 mm spacers in passing so he might have been using 320 mm discs. Take a look at your bike and assess how easy it's going to be to remove the calipers if there was 5 mm less space between them and the wheels. Maybe unbolt a caliper and watch as you slide it off the disc. The K9 calipers are smaller but the difference isn't huge. At one time the K9's had disappeared from ebay but I see that they're back. Pay close attention to condition as there's a fair chance that they came off a wreck.

The K9 piston diameter is smaller so a smaller 17 mm MC is also needed. You could use a K9 MC or the Brembo 17RCS if you have the money.

P.S. Note that a larger diameter rotor will be heavier and have greater moment of inertia.

 

I found a couple of calipers. Does a direct fit give some trouble when not changing the MC? Otherwise it becomes a big conversion and don't want to change the whole system.

 

The caliper-to-MC area ratio for K5-K8 is 22.7 vs 27 being considered optimal. The K9-L1 calipers reduce that to 21.3. But the K9-L1 MC will raise it to 25.3. The 17RCS raises it to 26.8. I haven't bothered to look but don't recall a used K9-L1 MC as being very expensive.

Note that the K9-L1 calipers use the same pads as K5-K8. The Tokico monoblocs were also used on some Hondas, but with different pads.

White wheels look neat but you have to constantly clean them. Black gets just as dirty but you don't notice.

 

Thank you for the explanation. I think I will let the original setup like it is but only with a bigger disc when the calipers will come off easily. I will remove my caliper tomorrow and will look if a bigger disc will fit.

I thought it would be a quick swap

If you have all the parts it would be a quick swap

Now in my experience, removing the calipers in the OEM setup is IMO already pain in the,...
Yes it can be done, but I don't like having to twist the calipers or put a screwdriver between the pads and the disc to create enough room between the pads, so it's easy to take off the caliper without hitting the rim (Paper masking tape is your friend in any case)

 

Masking tape is a good advice. Hope that taking the rim out isn't going to be a weekly thing for a street rider 😁.

Fitting a new MC isn't much work either but will keep it stock.

I have spend a lot of money at this moment. Needed to buy all new gear cause started riding sinds 17 years so everything needed to be replaced.

Fitted a nice Garmin Zumo XT navigation device to the bike with a custom bracket, and soms new parts like bolts, gear lever, alternator cover and so on.

I have ordered a new clutchcover nut but it is in backorder. You can see in the picture that it has some paint damage. That needs to be replaced.

The only thing that is left are the brakes and hope to get soms spacers soon. Ordered soms spacers and if they are the right ones I will place the partnumber in this thread.

 

Interesting that you seem to be convinced that some how you need a 5mm larger radius disc, and that is going to make a noticeable difference? Let us know if you do this. It would be hard to quantify this objectively however?
I'm not sure what your goals are.

 

Yeah, makes no sense getting bigger rotors and leaving the weakest link (M/C) stock.

 

I like big rotors, have got them on all my belongings. The mountainbike an my Volvo got bigger brakes as the came with from the factory. I know I am not the one who makes the most use out of the brakes but just like having a 10mm larger rotor if the cost are the same for the rotor. I know that stock size with other pads give a better bite.

Just my thoughts, same cost (accept minimum cost for the spacers) because I need to buy a new set anyway.

The Brembo T drive and brake pads are the same money as the stock rotors with pads.

The Brembo HPK version with brackpads are 100 dollars cheaper then an original set.

Brembo doesn't have any price difference for the 310mm or the 320 mm versions. If it gain any benefits the 320mm would be the favorit. Only for looks it would be a nice thing to do. The brakingpower would be a margin, if you could even tell.

I am aware that if I wanted a big upgrade I could better place a MC and monoblock calipers but that conversion I had not in mind.

 

I use stock size Brembo ORO on my racebike with K9 calipers. Never had any fadig issues and I am a little faster than the average trackday guy

 

I have ordered some 310mm HPK brembo discs and some Brembo SA brakepads. The bigger rotors would indeed be a pain to place mount the calipers in the rim.

The discs are in backorder and will take 11 weeks to arrive. Fortunately the brakes work fine so I can ride my bike till the time the arrive.
