    Default RDA Brakes, Protex?

    Ebay searches is stumbling upon discs made by these guys;

    RDA Brakes

    Namely; Renault Virage 1 4 1976 1980 Front Disc Brake Rotors DR345 Pair | eBay

    And these things by Protex? Renault 17 R17 TL TS Gordini 1973 1976 Front Disc Brake Rotors DR343 Pair | eBay

    Has anyone had any experience with any of these? I don't suppose there is anything really too difficult about a rotor..

    I have bought disc rotors off Ebay before and not had any problems, although I have not bought from that seller.

    Their feedback is pretty good, use Paypal to pay and you should be pretty safe.

    I've used RDA (Rotor Disk Australia) almost exclusively on a number of vehicles from Toyota Vans to Audi A3s and Honda Accords.

    I've never had a moments problems with quality or compatibility and the pricing is excellent.

    I've used EBC pads made by the same people too. Although the pads can be pricey- but premium quality.

    I buy them through my local brake trade outlet . Better Brakes

    The R17's and R12 rotors aren't the same.
    If memory serves, the R17's are ventilated discs and the R12's a solid discs.
    If you're going to use a R17 disc on a 12 you'll probably need a different (wider) caliper and it may not bolt up to the existing holes on the back plate. Check the dimensions before you buy.
    Others may have R17 discs on a 12 so would be have better knowledge of what's involved.

    But as the rotors on a 12 bolt onto the back of the wheel hub, changing them involves removing the wheel hub.
    Not a half hour job so give yourself plenty of time.

    I confess that was going to be a future question. But knowing parts exist at the moment locally, and that they are ok, is a bonus

    For those that install the vented brakes from 17's onto 12's, are you able to bolt the rotor onto the existing 12 hub, and use the mounting point for the 12 calliper with a 17 calliper? Or is it find some 15 / 17 hubs for this to all work.

    You will need the R15Ts/17TL hubs; calliper brackets; callipers as these different from the R12.

    The easiest way to to find a R15TS or R17TL that is being sold of because it is to rusty or been in a serious accident and cost to much to repair and you will have all the parts for all the conversions, motor, brakes and suspension.

    I've also used RDA discs and they're fine.

    I don't recall R12 brakes being less than very adequate? Track use perhaps not but.....

    Just curious, why bother?

    I have been told by a locally known R12 competitor from years past that the rear drums from an R12 station wagon or R15/17TL are actually better than the rear discs on the R17TS/G's when fitted to the R12/17 range of vehicles. Especially for hand brake turns. In Australia where we don't have the continuous use like in European Alpine rallies perhaps they would be ok. I have to say I did not heed his advice and I fitted rear discs to my R12. Never noticed any difference between the drums and disc rears for normal use even on the track. The events were probably too short to heat them up enough to introduce fade. But if you change the engine to an 807/844 then the law would require the fitment of the brakes that was fitted to the car the engine came from. Even if a hot Sierra motor was fitted I'd definitely up rate the brakes to at least vented front discs and wagon drums, just to be on the safe side. If you inadvertently killed someone I am sure the law would not be on your side if you haven't up rated them.

    In QLD back 20 years ago there was a Dept of Tpt bulletin that said what was required to up rate an R12 to R15/17 motor and basically you had to change all the different suspension bits and brakes to those on the donor car.

    I have RDA discs on my R17TS and they have been fine.

    I once towed a trailer full of concrete slabs with my R12 wagon. One stop and the brakes said, 'I'm out of here wheels, you coming?'

    By the way the R17TS/G has a large double acting vacuum unit. The R12 has a small single acting unit. I should also say the R17TS/G brakes are as good as any modern car requiring only a feather touch to operate the brakes. They must have been a revolution back in the early 1970's.
