molycarbide front rotors

[235rwkw]

just ordered some new front discs and pads.

been using dba slotted and formula ferodo for a few years. discs are pretty well worn now and need another machine badly. not sure if can take another one.

So just ordered molycarbide slotted discs for the front.

also going to try EBC green pads for the first time, as good as the ferodo are they are damn dusty pads, maybe the EBC maybe less so. dust could be reduced just with the moly discs, but may as well give these ebc pads a go. supposedly around the same specs temp etc.

now for the good part, love my brake supplier. molycarbide discs front $240 a pair, and EBC green pads $115 set... ferodo pads are not much more $120 set.

Discs are the same price a slotted DBA's at other shops for moly rotors. :)

He has really looked after you there with those prices but i still have reservations about greenstuff pads being used on larger cars.

ferodo formula are a great pad but produce loads of dust in a couple of days. performance wise fantastic. ultimate are supposedly worse for dust.

what do you recommend that has at least the performance of the formula pads but less dust? redstuff perhaps? want a decent amount of initial cold bite for the street, no good if you can't stop the first time for some kid down the road of something. they are in but not picked up yet, maybe able to change the pads.

wear maybe less on these moly discs take a little more to warm up pad matching is unknown to me for these.

I am not aware of a better stopping and dustless pad .I run the formula pads and think the dust isn't that bad .Sure there are less dusty pads but they don't stop as well and this is the problem i think you will find.I get many phone calls from people who want the so called perfect performance pad (stops well and is dustless)but we still haven't found it.
I know that these days with performance pads we have to accept the fact that dust is an issue and until someone perfects the issue i would rather stop better than be worrying about dust on wheels that can be cleaned.
:bravo: There is a new range of Bendix performance pads available to Race Brakes Sydney and we should have them on the shelf within days:bravo:

as much as i can find out so far the friction co is .46 on both the ferodo and ebc green and they both run the same temp max. although as you pointed out the ebc were tested/designed on a car at around 1200/1300kg the ferodo work on heavier cars well did for me anyway.

the ebc red are for heavier cars but the red are not kevlar they are ceramic. not sure what cold problems they will have as such at least std braking would be ok, increased when hot.

I understood the greenstuff to be for cars under 1000kg but the only real way of finding out as all cars and drivers are different is to try them and see how you like them for yourself as everyone will have there own opinion anyway.Good luck.

They seemed to work well in Duncan's Monaro at Wakefield. I have used them once too, and they seemed ok.

[235rwkw]

thanks almost changed back but i might try them still, i don't push hard very often anymore. if i don't like them i change back to FF, give em to my son he has a commy they will fit on now.:yep:

PS for some numbers FF have lasted about 40,000 k's so far and never faded. had some hard braking at times.

dust after a week when i wash the car i get black rivers of dust washing away the grass stays black for a couple of days where the car was. th back ones with normal pads have bugger all dust

might be ok for me then although he has bigger brakes too....

I used greenstuff on my VT a few years back and was thouroughly disappointed in the " less dust " attribute that was offered....

IMO they were as dusty if not dustier than the Holden Genuine pads that were previously fitted.

well that a good sign for me, oem pads are a dream compared to the black dust from the formula pads. i'd be happy with the same as oem dust.

maybe just my combo of dba rotors and FF pads that isn't good for dust.
just this morning when checking the distance from the strut to the rotor for a dial indictor bracket setup i got cover in black dust from the rim

BTW this RDA site has good info on brakes, noise, fitting, torquing wheels nuts correctly (i always torque them up) etc.

[235rwkw]

Fitted the molycarbide front disk rotors on the w/end and EBC greens.

Fitting the discs on rhs measured the runout tried all 5 positions 4 of them varied by up to .15, best was position 4 at .05 max runout. LHS first go got 0 runout so didn’t check any other positions.

Fitted the pads without the supplied anti rattle backing, just used CRC anti squeal compound. PS These pads come with a bed in coating on them now.

Did 10 stops of 60kph to 10kph to bed in, let cool and did it again.

So far stops smooth and easy (minimal efford) and no noise. Not tried to test max braking yet, but feel like it will be good.

Not much driving yet apart from too work today, only 15 mins. But bugger all dust so far, time will tell, by the end of the week I’ll know if they are better for dust or not over the FF pads…

I found greenstuffs a good budget option, i was using the stocker brakes at the time (albeit with DBA4000 rotors). i found they lasted about 100 laps at wakefield, pushing reasonably hard.

I would be interested to see how these rotors go at a track day

[235rwkw]

well dust report these disc and greens are about half the dust so far.

don't seem to have the initial hard grab of the FF's, but not done over 300 k's yet either. greens seem to be more progressive and to stop fast require more pedal pressure than FF's. it either the pads or the discs so hard to compare pads with a rotor change, the harder molycarbide could be the reason also.

[seldo]

I'll be interested to hear how these go.
I had Greenstuff for a while but found they were very dusty (like annoyingly so) and after about 10,000kms had really chewed the discs. but, they worked well enough.
I note that when the Chance of a Lifetime thing was going they used Greenstuffs exclusively on all their Lotus Esprits

who makes these rotors?

[235rwkw]

RDA makes em....

i accidently said dba on another forum rda dba, its RDA anyway....

BTW this combo seem to really be almost dust free, at least 1/4 the dust of the old combo. probably due to the rotor being harder. dust is a combo of pad and rotor wear. i went two weeks without a wash and could still see the polish rim edge as shiny looking, before it was black in 3-4 days..

was gunna say i got them on my car too with ebc greens and braking performance is great have to try reds when this set wears out to see if any difference for the normal motorist

they don't seem to be advertised or listed by RDA yet, but they have them just have to ask for the moly ones specifically. my supplier didn't even know about them until i asked, only knew about the normal slotted RDA rotors...RDA also have a normal rotor thats slotted and dimpled, buts its not moly atm...

ATM the moly ones can be identifed by th stamping on the back or the wide curved slots on the face

moly probably has an advantage for the track and race compound pads, lighter rotors but harder compund so won't wear as quick as normal rotors with rotor hungry pads.

[HSVSV6]

yeah that arent listed but i know the numbers i a rda prem dealer in wa long story to why thtey havent advertised them yet

[235rwkw]

very dust free combo still even less dust than at the start now.

[HSVSV6]

i must say i agree found them to have no to minamil dust output im using the greens and the brake response if huge got told of by cops for stopping to quickly on an amber
