@Seven76, a part les rondelles de centrage, rien de chez rien pour trouver l efficacite ? Tu as change les disques en meme temps ? Quelles plaquettes ? <!--QuoteEnd--> </td></tr></table> <!--QuoteEEnd-->

il me semble que ce LF anglais se plaint d'un déséquillibre entre l'avant et l'arrière ? et d'une pédal de frein devenu "trop dure" avec dosage difficile non <!--emo&-->[img]http://www.forum-autoroule.com/html/emoticons/icon_question.gif' border='0' style='vertical-align:middle' alt='icon_question.gif' /><!--endemo-->

<!--QuoteBegin--><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td>QUOTE </td></tr><tr><td id='QUOTE'><!--QuoteEBegin-->I replaced my std. front calipers with HiSpec Ultralite 4-pots (and grooved solid discs and 1144 pads) just before this w/e's Tour7 Haggis tour - many thanks to Frank for bleeding them one-step closer to working properly, by the way...

They've now done 1000ish miles - most of which have been m-ways, but also some hard Tour7 driving (admittedly mostly on wet roads...)

My initial thoughts are that they are taking a hell of a long time to bed in (I've nothing to base this on as I've never started with completely-new discs/pads and calipers... - it just feels that they should be working better by now).

I've also been experiencing rear-end bias - not sure if this is entirely due to the bed-in (rear discs are unchanged, rear pads were changed for bog-standard items a few weeks ago) - this was damned-scary, especially in the wet. It has improved a bit with useage, but I still think the rears will lock before the fronts.

<edited to say> Rears are std. Sierra - the only recent change was to fit flexi hoses at the same time as the front-upgrades.

THe pedal has also been quite spongey and requires a fairly-long push under hard braking - this is with the standard MC and high-ratio pedal (I think - I understand these were standard-fitment on Academy cars...)

I'm not unconvinced that the pedal gets spongier with heavy useage too - but this might be something to do with the bedding-in as well...(?)

The piston-area is not too-far different from the JW Alcons - and *these* are designed for the standard MC and rear brakes, AFAIK.

It has been suggested that as the rears are still receiving the same amount of fluid - but the fronts have a larger area - the rears will *not* be balanced and I'm not actually going to get to the point of really using the fronts without the rears locking up...

Sooo - so far, not so impressive. How long should I wait before investigating fitting any of the following:<!--QuoteEnd--></td></tr></table><div class='postcolor'><!--QuoteEEnd-->
