what rotors and pads are available for my 1987 leone RX?

I see that DBA make the front rotors, but who makes the rear ones? any available in slotted? going prices?

any decent pads available? going prices?

thanks.

Off the top of my head they are only 226 something mm diameter and only 10mm thick . Your call but a disc that small isn't gonna gain much if anything from gas grooves because the cars are light and these rear brakes don't work very hard .

I swiped my spare pair off a front wheel drive Vortex at a wrecker .

Cheers A .

PS if all else fails try Subaru .

DBA used to list rears, maybe worth a call directly to DBA and see if they can still do them?

what about pads? front slotteds?

yeah i know slotted rotors with such small rotors wont make much difference, but i'm of the opinion that every little bit helps, and for safety that little bit could be the difference between life and death.

True, but how hard are you really driving? - you may be pushing the boundaries too far, then what happens when you get this little extra bit - push the car an extra bit harder and end up in an even nastier stack?

Food for thought.

stop flaming him!!

andrewt put slotted on the front of his rx....now i know his is an ej turbo but i had a drive and thought the slotted and new pads where quite good...a noticable increase in pulling power over stock crap

i dont know the part numbers maybe andrewt has them

will never be driving my rx hard, that's what the other car is for, and that's why i visit the track

1 simple reason for wanting the best stopping i can get - 3 1/2yo son.

will try pming andrewt. thanks.

My new slotted front rotors are manufactured by RDA which by all accounts is as good as DBA.
The part number is RDA641S.
According to their website, there entire range of brake rotors is available with a slotted option.
I have not replaced the rear discs so I'm unsure if they do them but I'd say the likely do.
I think Subarino and Matatak tracked down some replacement rear discs actually.
RDA's website catalog is not available unless you are one of their authorized resellers....but they are cheap enough to buy retail anyway.
I bought mine through Odin Auto in Balcatta.
Best bet to track down the correct ones would be to ask for rear discs to suit a 87 Vortex Turbo 4x4. People get confused with RX, it's rarely listed properly in parts books.

Surprised you thought the brakes were good that night Dave, they hadn't even been bleed properly. Maybe it's the difference with rear discs in an L series you were noticing. Personally I've noticed hardly any difference to the braking in my wagon (which had standard brakes, drums at the rear).
I think the slotted feature is mostly to reduce brake fade in emergency stop situations (like from 150km/h to zero) and I haven't really tested this.

Naturally 4wheel discs with slotted is about the best braking you can get in an L series...if you stick to L series brakes.

You can mess around with swapping master cylinders and boosters, even trying to retro-fit bigger calipers but these mostly will just change the brake pedal characteristics to make it require abit less pressure from your foot to stop etc.
But the only REAL way to increase braking power is to go for larger diameter rotors.

If you are serious about increasing braking power and the safety of your passengers, consider a Crossbred kit with Liberty or WRX brakes - the increase in braking power is simply phenomenal. Borrow a WRX and test out the brakes - they are amazing, then imagine them stopping a little RX which is about 400kilos lighter. Something to think about.

I will be doing it as soon as possible, these slotted rotors were just a temporary thing, I think they cost like $12 more than standard ones so I thought I'd give them a go.

shotgun your front slotted when u go crossbred andrew

im fairly sure you can still order in rear rotors- even slotted ones as i remember seeing them in a parts book not so long ago. i do believe ive heard of some american dude putting bigger rotors on the front- i think from a nissan silvia? that rings a bell. might need at least 14" rims tho

matt, just give shaun a ring he dose rda gear also. its cheep as chips

twilightprotege · Post by **twilightprotege** » Tue Apr 15, 2008 10:26 pm

will give rda a call and have a chat, thanks for that. i'd like to go bigger rotors, but wanting the use the car for 4x4ing makes that difficult. i'm using wrx rotors (dba 5000 series) on my mazda astina with rx7 calipers. now that's braking!!! they just fit within 15" volk te37's, ie 295mm rotors and 4 piston calipers.

now, pads. what's the go there?

i have a bent disk rotor.. how difficult is it to pull the thing off ? i havent had to muck round with brakes before so i'm a bit unsure..
is it possible to repair a bent rotor by machining it or something or better/cheaper to replace ?
cheers

Depends how much meat is on your brakes. If there's heaps definitely machine them. If they're going to end up close to unroadworthy thickness then just buy some new ones. You'll save alot of money if you pull the rotors off your self and just take them into a shop, or get a mobile break dude to come around.

since i started this thread, i have been able to get front and rear brand new RDA rotors for under $300. i was pretty happy with that price
