My Carnival from 2002 has the strange habit of making a grinding noise when I brake on the highway. The noise accurs after a couple of seconds.
Probably the brakes aren't sufficient for this type of ussage. I tend to drive a steady 140/150 km/h. When I'm entering Germany or France it's even worse. I cruise at speeds of 180/190 km/h. I've already installed new discbrakes and pads but this doesn't seem to help. Is there anyone who can recommend a special brake manufacturer? The problem is probably solved when installing special groovedand drilled discs. But I'm not sure. Is there anyone with a simular experience?

In modern disc brake pads with no Asbestos in them you will find they grind when using them, my old Mercedes Sprinter needed new pads on every service and new discs on every second it wore them down at an alarming rate (this was all four wheels) The Kia Sedona is not so different, it's over two tonnes of vehicles being brought down from high speed. I suppose the only way to reduce it would be to drive more gently, plan ahead and reduce speed by slowing down rather than harsh braking. :thumbsup:

Not that you;d ever catch me doing that mind, Pepper the last of the late brakers!

180/190 km/h (105/115 mph) Thats a bit quick for a Sedona? I've only legally had mine over the 100mph once (110 :haha: ), foot was firmly planted on the floor, the revs are approaching the redline and the fuel gauge starts to get that empty look very quickly :eek:. Not surprised about the brakes I found they due tend to vibrate alot when used in anger at these speeds. Agree with Pepper with regards to braking :thumbsup: you need to be gentle..

Specialist pads Here (Green stuff) I use them on my F2 Evolution...

Thanks a lot for the good advice, about braking that is.
I know about the asbestos story, I'm a a garage-owner myself and find all of this stupid environment-regulations horrible.
But the noise is more of the noise of very hot discs and pads. They don't seem to "breath" enough of thend not to cool down as quick as I need them to. I'll probably install some other drilled and grooved discs and see what happens...................................

And about the speed. It's really what the spedometer says. But mine is probably quick. Last february I had her on 200 km/h in Germany. I had a very sick child in the car and needed to get home as quickly as possible.

It's a good thing you never have seen my other car.........................
(first edition SAAB 900 T16v (1984) tuned up to 200+ BHP and a torque of approximately 450 Nm..................)
As you can see this is my pride and joy.

Sorry :eek:fftopic: forgot to mention the speed reading was taken from my portable Sat Nav system. Speedo was reading between 5 - 8 mph higher :) so with you on the top end.

German motorways :thumbsup: Fantastic :thumbsup: and people pull into the nearside lane when they realise a faster car is approaching in their mirrors. Not like the MLM's and endless outside lane convoys in the UK :angry: :angry: :angry:

Any suggestions about the brakes? :thumbsup:

IMHO..
The main issue with Sedona brakes is they are a bit small for such a large vehicle, as your at the extreme end of the perfomance envelope for a sedona you are going to have some issues.
You need to get more cooling air to the brakes, if you can find some Brembo hi-carbon discs and a performance pad, add in some DOT5.1 fluid and you may have a better time at speed.

Pads I've tried in others car:
Ferodo DS2500
Mintex C1144 compund
EBC Red Stuff V2 ceramic

One of my suppliers is looking into the problem.
I'll probably install a couple of grooved and drilled discs, together with a pair of heavy duty pads. This probably solves the problem. It's clearly a problem of not enough ventilation. The resonance (grinding sound) only occurs when the diss are hot.

Let us know how you get on please, as I'm sure some of us would be interested in uprating the brakes too. and Holland ain't too far away to get stuff from.

When I had this problem with my Sprinter I went through about 20 different sets of pads until we found some that didn't grind and once we got them we never changed, But it seems the Company went out of business.

Oh and boy did my sprinter grind the brakes, 3500kg + of tuned sprinter took an awful lot of stopping!
