c63 amg going on a sl60 amg

[biturbo]

Ive just bought a full c63 brake set. front and rear calipers 2 piece front discs vented and drilled and pads.
Was looking at upgrading and when i totalled the price i got this for about the same as upgrading what i had. Interesting part now is trying to get it to fit. I know the guys in the states have managed to do this as a few are running the 6 pot and 8 pot brembo calipers on the r129. Anyone done this in the uk?
The sl60 amg should now hopefully stop like hitting a tree. Do i have to change the brake servo?

The SL60 stock brakes are perfectly good. I imagine AMG know a thing or two about this.

 

[biturbo]

maybe, but in 1996 they knew something and then in 2008 they knew a little more.

Once you have defeated the friction between the tyre and road surface a brake can add no more stopping power.

Well i dont have tyre lock at the moment at any point. Tyres are top quality and huge. I wasnt happy with the breaks before, so ill see what difference it makes. From what people have said before and what i have researched its gone from 320mm fronts to 360mm 2 piece drilled and grooved. The proof will be in the pudding. If its no real difference ive just bounced my money. If however it makes a big difference then

Should make a big difference, as you say the brakes in 1996 are not going to be a patch on C63 one's.
Will also look much better

Have you checked what your insurers think about DIY brake mods?

Beat me to it....

Upgraded brakes will make a difference, they will make the car slower, ride and handle less well.

Still, they should look good...


The O/p doesn't need upgraded brakes, just the faulty ones fitted at present need fixing. If they can't lock the wheels they are dangerously under performing.
If any upgrade is really required to assist stopping power, it is to renew the springs and dampers...after fixing the brakes, of course.

It added absolutely nothing to my insurance when I upgraded my brakes to BRABUS set earlier this year.

EDIT: Last year that is

 

[BTB 500]

Insurance impact will probably depend on how 'modified' the car already is. Needs to be checked out though.

Unless you upgrade the master brake cylinder, you will have the same amount of fluid dispensed to calipers to push the pistons, so no hitting a tree effect I'm afraid

That said my personal experience with new brakes on is that they grip much better compared to stock, or in other words I had to push pedal much harder to stop with stock brakes.

Whether that's an actual improvement of stopping distance or simply a foot feel I will see in the next few months by running a few low-scientific start-stop tests with stock/BRABUS brakes on, which I will try to record and put on Youtube.

On a side note, I remember reading somewhere that BRABUS brakes manage to stop W211 E55 14 meters (or smth) earlier than those of AMG. Except the actual calipers, discs, hoses and pads everything else is stock.

EDIT: I didn't explore this further but you may want to look into fitting an actual C63 master cylinder.

How unless they are binding or unless they are not seated properly?

Ive just driven a r129 Sl500 today and the brakes are even worst on that than on my sl60 amg so i think my opinion is more to do with the fact that im used to high quality brakes on the s600 and the sl60 amg seems, well rubbish. The faster and heavy the car the more difference you see.

'if having better breaks as some people are saying will make the car worst. Then why dont the latest AMG comes with 97 brakes, ATE i think they are.

Get a C63 AMG and then ask for the 'super AMG pack' and ask for retro fit 97 Brake calipers and brake discs. They will make the car faster, ride and handle better, apparently. Also there is no benefit from getting bigger brake discs or calipers or having them drilled or vented.

I've got classic insurance, but i dont see a problem in something being professionally fitted not a DIY job, but ill check that out this week.

 

[horgantrevor]

yes the brakes will make the car stop faster and this will be due to several things caliper ,pads ,disc quality , and tyre's

it should look great and work great as a DIY job its easy if you know how and have the tools and the reward will be great

go for it post some pictures i cant wait to see the result what are you doing with the old calipers and discs i bet some people on here may want them

and last but not least if you want to improve the braking even more change the brake master cylinder to a higher spec and the pads

Well i was with you on the conversion mate ^^^

 

[BTB 500]

I don't get the 'stop quicker' comments, unless the brakes you have now are incapable of locking the wheels when fully applied (in which case the car wouldn't need ABS?!)

I thought brake upgrades were primarily aimed at improving 'feel' (better hoses) and reducing fade etc. under repeated heavy braking (e.g. track driving)?

Don't think I've ever had to do an emergency stop in my SL - will give it a try sometime!

 

[BlackC55]

Why don't you explain DM

 

[biturbo]

when i say the s600 is better i mean it doesnt get cooked 'brake fade' and the bite feel on the pedal is instant and you dont have to press hard and it all stops nicely front and rear. Both cars weigh 2 tonnes give or take. Id say the s600 stops in 80% of the distance the sl60 did at say 70mph to 0, and you can do that many times no difference. A couple of hard stops the sl60amg is rubbish. Discussed before im doing all the mods brake lines brake fluid etc. I just thought for the price i paid its the complete set swap over.
