front and rear disks and calipers w202

[mr_ace5288]

could anybody tell me where i can purchase a set of brake discs and calipers for my w202?

i have just put on a set of 19's and the spokes arent as thick as before therefore can see the puny discs and rusting pads.

would just like a more SHOW package that looks pleasing, actual braking power etc need not be top spec like as im a casual driver and its only a modest 250 diesel

Try club member jimmy.

He specialises in brakes.

If you want to go for a larger disk you will require a larger caliper support.

Hi
can I just put this point in.
Don't try and fit larger diameter brake discs and callipers, you will find that the tyres will become easily overloaded and lock up very very easily.
I also own a turbo MR2 as well as my c class and another MR2 owner tried it and nearly scared himself to death before hanging back to the standard ones again. It changes from progressive firm pressure to stamping on the brake every time you stop.

but they look cack behind the rims, can barely see them, and what you can see is kinda rusty lol anything to improve the looks?

 

[jimmymack]

well, I suppose if you wanted to spruce things up you "could" paint the callipers but I don't think they look very cool like this myself.
In hindsight, perhaps different rims would have been better?
just out of interest, hows the handling now?

 

[mr_ace5288]

the handling around corners etc i find really better, they do a full cut etc still. and ride height as mentioned is rather floaty, only problem is it tends to tramline, any idea why?

 

[jimmymack]

if the tyres are lower profile than standard, they will have less flex and will usually give a harsher ride, if the tyres are wider than standard then they tend to follow the ruts in the road as they have more grip and it is a case of the tail wagging the dog. Usually the bias is towards the driver and the steering is weighted accordingly, change things around and road feedback is altered.
Manufacturers do spend a lot during testing to find the perfect compromise between handling and astethics, however, once in the hands of the new owner, their preferences might not be the same as the manufacturer and thus a whole industry has grown to cater for it

One of the main reasons for larger wheels is to upgrade to larger brakes for extra stopping power.

the MR2 problem sounds more like a brake bias problem. Were all the brakes upgraded or just the fronts. Just upgrading the fronts on a light car will cause them to lock up.

The chap changed all 4 disks and callipers from a Supra, took a bit of modification to make the callipers fit I believe but the brakes were so sharp that he was constantly locking up.
The relationship between calliper, disk diameter and tyre is quite important to keep the balance correct between effective braking and overload

If that's the case why are AMG cars fitted with larger disks and more powerful callipers?

 

[jimmymack]

its all about design.
each cars components are concieved with best compromise in mind. A car that is capable of 155 mph will have different suspension components, geometry and braking characteristics than one which is designed to do 120, if you were to put the lower spec braking system on the AMG then it would be under specced and over worked, prone to fading and simply not up to the job, swap them over and have the lower spec car with the uprated braking system and it is the reverse that occurs, a dab on the brake will transfer into a sharp stamp at the wheel.
Upgrading to grooved discs is a viable option if only to keep the pads glaze free, but increasing the disc diameter and adding heavier displacement callipers will only lead to the loss of progressive braking.

...swap them over and have the lower spec car with the uprated braking system and it is the reverse that occurs, a dab on the brake will transfer into a sharp stamp at the wheel.

If that were true then "a dab on the brake will transfer into a sharp stamp at the wheel" on AMG models too, as they are 99% the same as all the other cars in the range, except obviously for the brake components. I don't think that's how it works!

Could it perhaps be proposed that there was a certain amount of user error involved in the faux-pas?

 

[mr_ace5288]

lol. correct if im wrong but wouldnt braking at 60mph in a bmw m3 be the same as a bmw 318 doing 60mph?

even though the m3 has much more power the braking distance if the engine was idling of both cars with same brakes should be the same ryte? (other than minor weight difference)

so could anyone help me srt out a couple of options on the market for uprated brakes and calipers etc for a mercedes w202 96 model? much appreciated. not looking to "brake" the bank, more looks than shooks

Not sure if this will be of any help but what do you reckon? About 9th post down
