(help) FIBER DISCS & STEEL PADS

Postby Dan » Wed Nov 10, 2010 10:30 pm

hi,

i just fitted megathek fiber discs & steel pads,all is correct stuff,brakes them selves (calipers etc) are all new,(single piston calipers)
megathek expert

my questions are,do these take time to bed in?
cause the front ones are not bitting as good as i expected,the old steel discs were locking solid,excellent actually,i thought these would be much same only wouldn't heat up as much.


these seem like they either need to bed to work properly,if not they are just not worth a damn

in fact what are the main reasons for this paticular upgrade?

i would like to hear your opinions.

thanks
dan

Epoxy wth steel brakes a little less but are more progressive ( in the sense you can avoid locking the wheels ) than ferodo pads and steel.

After initial bedding in I am sure you will have no problems locking the wheels if it is what you want.

The reason why people use epoxy discs are in no particular order:

Less weight
it doeasn't get stuck in the wheel carrier because the epoxy is less hard than alluminium
epoxy discs don 't bend as easily as steel discs
they are cheaper to produce for the manufacturer wich translates to a lower price to you

I would say that if you walk around the pits epoxy users are 70 % or more of the total.

The servo is too weak sounds to me , or ( but I think you would have spotted this ! Air in the system , oil on the pads or discs and other obvious things.

One other thing could be that there is too much gap between the pads and the disc but if you reduce this gap , when the system is hot it will cause jamming of the brakes because of volume increase of the fluid , if I am not mistaken the signgle cylinder system comes with the old Collari master that is a closed system.

hi,

thanks for your opinions.
the car is brand new,just done a few race days,the brakes are also new,megathek...

the brakes were perfect,i changed to epoxi discs & steel pads for a more improved brake,but now i don't know they seem weeker...

maybe a little time to bed them in.

seems like i can easily twist them by hand which is anoying.

i had car out today for test,they were a little better,like i say bedding in maybe might help too... :mrblue:

i did re-bleed system just in case.

i have a race day tomorrow so i will see how they go.

thanks :mrblue:

When the disks turn black, don't clean them.

They work better the hotter they get (within reason) where as steels work best cold.

Fibre disks don't warp due to heat (I done quite a few)

I wouldn't swap my RB's for anything else.
