Till now nobody came up with something better then the standard as far as I know.
Jespers v6 Murena has custom brakes I think.But I agree with Michael on this one...I too wanted to .. mostly to get ventilated front rotors.... but "if it ain't broken... don't try to fix it"... As Roy has pointed out to me once," a Murena will happily lock up all four wheels in the dry... on ANY surface...". and fading doesn't seem to be a problem.You should also consider why the murena has discs at all four wheels.. and why the rear rotors are not the same used on a 2..2 as on the 1.6...The extra weight of the bigger engine dictated the larger rotors to hold the extraheat So..Midengine layout with 35/65 (at best) weight distribution,unequal tracking, different tire widths front and rear..Do you really want to experiment with a brake set up that has clearly taken some considerable considerations from Matra to get right in the first place?Black/green stuff(tm) pads and maybe some x-drilled rotors are as far as Im gonna go.
Oh, thought fading and weak brakes indeed was a problem on the Murena.....Thats why i had plans of upgrading the brakes...
The only thing that bothers me is the rattle and sticking problem at the rear
And I have also heard from some that changing to steelbraided brakehoses removes some of the spoonginess in the pedalmotion. Because they flex less than regular ones.Can anyone verify or discredit this...?
