For those who do not recieve Slice, here's what you missed:
I should say that £50 ea. is really the top end price, they may very well come in at a fair bit less I hope.the one and only reliant-reviver, overlord of all things rusty, underpowered and wedge shaped wrote:Vented brake discs
Next on the small sports agenda then is vented 223mm brake discs.
It came to light earlier this year that both GW and QRG had run out of the discs employed in the upgrade kits they have been supplying for the past years, with the last batch made in 1999 and having finally run out. Now despite what some misinformed Ebay vendors would have you believe, there is no off the shelf compatible disc from another vehicle which will fit, vented or otherwise. The SS1 solid discs were specific to the car, and so were the vented type made for the aforementioned dealers. Based on the previous cost of having them made, it seemed that this was going to be a non starter due to the massive minimum batch quantity predicted. However, after discussions with the chaps at Graham Walkers Ltd. there is now the possibility it will go ahead. A mimimum quantity of 100 discs / 50 pairs is required, Graham wasn’t overly keen on investing what is a considerable amount of money in stock that may sit unsold for years. I am trying to assure him otherwise though. With a large number of cars already using this setup out there, and more people looking to upgrade, surely there is enough interest?
Discs don’t last forever, and if you use harder performance compound pads they start to wear out rather quickly , indeed I am getting concerned now about the future of the 2 sets I have.
For those not aware, these vented discs are of the same diameter as the standard solid ones. This requires the calipers to be either swapped for Metro Turbo items which are wider, or to rebuild the calipers, fitting one of the readily available spacer kits which convert the standard width caliper to accept the thicker vented disc.
The benefits of this setup are that there is no change in braking force, thus leaving the car’s brake balance as the factory intended and not requiring the rear cylinders to be changed for different sizes. They are of course more resistant to brake fade, and I find them more than adequate on my modified 1900CVH and 1800ti SS1s, having not failed to stop with them once!
It seems a lot of people unduly give the original setup a lot of bad press, when really it is due to poor maintenance. Old brake fluid, corroded or worn discs and cheap pads, will give a truly shocking braking performance. The problem with this is a lot of (usually new) owners immediately blame the design / specification of the standard brakes and venture off on the “I need a massive upgrade” route.
I will agree though that the original solid disc brakes can be overcome with relative ease if used in real anger. In my view the answer for most cases would simply be upgrading to the dealer supplied vented discs.
SO, whether you are looking to upgrade for the first time, or to change your worn vented discs. PLEASE get in touch, we need an expression of interest in this if Graham is going to front the cash for a new batch. The price is currently looking to be sub £50 per disc. Original Reliant solid ones are over £35 a side now, so there really isn’t much difference.
Anyway, FIRM interest on a pair.
