Brake booster - Vinay-RS - 04-13-2016

Hi Guys, 

I have heard that 7.5" discs are useless without a booster. So I was wondering how easy it would be to find a booster, what it would cost for a working example and whether it is actually necessary.

Thanks,
Vinay

I think it comes down to personal preference. The booster doesn't add any braking force, it just makes the pedal easier to press i.e. takes the strain out of pressing it. I know on my brother's old 16V that the 7.5s were perfectly fine with no booster, it just took a little added pressure.

That's how I see it. Other guys may say differently.

And the other info? Prices and availability?


RE: Brake booster - Jared Mk3 - 04-13-2016

Well, which booster are you looking at getting?


RE: Brake booster - Vinay-RS - 04-13-2016

One that would work? Honestly not too sure what would be correct. Since strictly speaking discs are a mod and I have no idea whether they would be mkI/II S or GT or GTS brakes. I figure a GTS booster would be suitable and probably cheapest.


RE: Brake booster - Jared Mk3 - 04-13-2016

S, GT and GTS 7.5" disc brakes are the same. Your brake master is the split one isn't it?


RE: Brake booster - Vinay-RS - 04-13-2016

It is the long one, yeah.


RE: Brake booster - Jared Mk3 - 04-14-2016

What I'd do is fit the discs and see what you think first, before committing to a booster. See if you can locate one in the meantime, fit and see if the discs are right for you and then consider fitting one.

More often than not there's a lot of hearsay about conversions and modifications, but the best way to try it is to see for yourself I suppose.

And I am guessing the MC is wrong for a brake booster?


RE: Brake booster - Jared Mk3 - 04-14-2016

I'm not so clued up on those split MC. I like the simplicity of the single line system with a rear limiter valve.

If you could find one, I suppose you could use the combined MC and booster like the later Minis had.
