Valvole proporzionali

[MOTORPUNX]

Qualcuno sa le differenze tra le varie valvole proporzionali?Se sono intercambiabili tra loro e che proporzionalità hanno (60-40,50-50,ecc)?
Sono diverse tra dischi ant+dischi post e dischi ant+tamburi post?Mi ricordavo che quelle Lude fossero 50-50 ma non mi ricordo dove l'avevo letto...

Aprila, fai una foto al tutto smontato e ti dico come fare per cambiare il valore.

Prima me la devo procurare,e già che c'ero ne prendevo una adatta...

Gay!

So che quelle per tamburi son diverse da quelle coi dischi dietro, e non vanno bene coi dischi. Il numero sulla valvola non indica la quantità di ripartizione. Ne ho un paio in garage, ma non ho nessunissima voglia di spedirle.

Stavo pensando di metterla sul'EG6 e concludere il discorso freni,ma non so se quella EG è già 40/40 come quella ITR

mentre su HT questo:
1725 valve (88-91 CRX with rear drums)
2040 valve (90-91 CRX Si) - used with 9.5" front brakes matched with rear discs.
3030 - 9.5"(small) - rear drum
3040 valve (91 EF hatch) - used with 9.5" front brakes and rear discs
4040 valve (90-93 Integra) - used with 10.3" front brakes matched with rear discs.
3540 valve (90-91 Civic Ex) - used with 10.3" front brakes matched with rear drums

Basically, any prop valve (30/40, 35/40, 40/40...) is going to act exactly the same under normal braking conditions. They will basically split the fluid up evenly, or at least as close as mechanically possible. What differs is under hard braking.

From what I've learned from growing up with my bro and dad is that the lower the number, the less fluid is sent to the rears, thus preventing the rears from locking up due to the weight transfer under hard braking.

What this means is, under normal braking the 35/40 and 40/40 are going to act exactly the same. But under hard braking, the 40/40 will send a little more fluid to the rears than the 30/40 or 35/40 would.

And if you're going to be upgrading your rotors in the rear later, you would actually want a 30/40 or 35/40 under hard braking, to keep the rears from locking up due to weight transfer during a hard brake.

Basically, from how I understand it, it's all about feel. If it feels good, keep it. If it doesn't, try something else if you can. 35/40 and 40/40, in my personal opinion, doesn't seem like a huge difference. The reason for the bias in a drum/disc setup is because the fade on the drums would be much more substantial than on the discs, this is because of heat in the drums, discs
