Disc Brakes

Post by Scoobydo » Sun Feb 12, 2012 9:52 am

I want to upgrade the front brakes on my MGZR. I would like to know members opinions on either the retention of the standard disks and just replace the pads (green stuff or Mintex 1155's) OR go to drilled and grooved discs with new pads? The car is being used for 12 Car and Nat B Road Rallies where you are on the brakes most of the time, or I am, and Autosolos.

As long as the existing discs are good I'd think it is worth trying just pads first as a cheaper, simpler option. Only then will you know if it's enough but you've only sent a few quid on pads finding out.

Are you struggling with over heating/fade on the 12cars? or do they just not seem to brake very well?

I can highly recommend going to ds3000 pads. Minimal wear on discs and work from cold. Minimal bed time. Better fluid is always a bonus.

They fade off dramaticaly and we've had a few hairy moments so it's high up on the to do list.

Who makes ds3000 pads and where from?

Just found they are from Ferodo available from Demon Theives but only ds2500 compound which is what, harder or softer?

I think but not sure, 3000s are softer. Best people to speak to is peter Lloyd rallying. Or if you can get the part number camberely auto factors can get them.

Try the basics first, braided hoses, new fluid, check the calipers are working fully.

Braking is a very personal thiing, so one persons ideal is not anothers. But for the cost of a complete std set of mg zs brakes I would try new std first then change bits.

I personally swear by a combination of decent pads (carbotech xp8's for me) and standard discs I can find.

I recently put the Brembo sport Max disks on my car, after I was told (by someone that should know) that they were one of the hardest disk compounds out there (along with Zimmerman) if you want to keep the standard size.

Always best to change the fluid on a very regular basis, I do it on a yearly basis (rather than the recommended two years).

Over heating can be a simple as using old fluid that has just got too much water in it to function well.

Also if you want to upgrade the size, if you have the 262mm, then you can upgrade to the 282mm very easily with a set of calipers and carriers from a ZS180 etc (I obviously don't know the size of your disks)
