brake dust.

Helen Goff · Apr 26, 2003

A question from my better half who has just cleaned my boxster for me......bless him!

Why are the front wheels always dirtier than the rear wheels?[8|]

he should know he' s a machanical engineer!!

Since he' s a machanical engineer, he will never know!! However, as a mechanical engineer...........

I asume it' s because the front brakes put more effort in to stopping the car?

BTW, after you' ve cleaned the wheels, put a good layer of wax/polish on, this will help wash off the brake dust in the future.

thanks i' ll tell him.

by the way he' s cleaned the hood looks like new.

So you sit in front of a PC all day, posting messages, while the ' other half' has to get on with the chores, like washing the car(s).

Bah humbug !

Ok, here is an on-topic Porsche post from me (I normally reserve these for other forums, but hell, why not try here).
I understand there are some pads that give out minimal dust. Pagid Greens maybe?
Anyone recomend one (that will still stop you when cold on the road) that gives out less dust?

It' s all down to physics! The inertia of the car is shifting more weight to the front end on braking putting more pressure on the front brakes. This is why sometimes the front brakes of cars/motorcycles/etc are more powerful.....

EBC " Greenstuff" seem to be the colour of the month for this requirement.

Guest · Apr 27, 2003

Do they actually give out less dust, or is it just green so is not so noticeable?
Or are they harder, so wear the discs faster instead!

I have used EBC greenstuff and find them very good replacements for standard road pads. They do reduce dust drastically, and they do work from cold.

I have also used them on track and was impressed, but whilst they did last 4 trackdays plus 10,000 road miles they did start to score my disks. I would not recommend them for heavy track use because of this.

On the subject of brake dust. Since my last service (including brake fluid change), I have noticed when cleanig the car that the front n/s wheel appears to have more brake dust on it than the other three. My immediate assumption was that there may have be some variation in pressure introduced during the fluid change (e.g. frt n/s working harder than the other three). I plan to conduct a rather crude brake test this evening - quiet stretch of road, firmly apply brakes and let go of the steering to see if the car pulls to the left. I wil also compare pad wear on both front wheels.
My question is - could there be another reason for this?

Yep

And you do get less dust and they don' t fade..

To my amateur mind this would mean that your front o/s brakes are not imparting the same pressure on the disk as the n/s. Could it be that the calliper is sticking or you have an air pocket in the fluid to that calliper? As you said, check your pads to see if they have worn evenly.

The brake balance on the Boxster is weighted towards the front (this is true for nearly all cars). Hence, the front brakes apply more braking power than the rear brakes. This generates more brake dust.
