係. 但而家個虛位仲勁. 不過, 仍可以勉強做到heel-toe.

coupeelvin

我記得你個brake不嬲都有虛位......

romeochris

做到 heel toe?

Simon

又唔會喎. 只要踩晒個虛位, 之後就可以好線性, 印多D就迫力多D. 慣慣地.

romeochris

快車會唔會踏到地板o家?

Simon

個迫力係好低, 不過, 日日揸住佢, 又唔覺係問題, 反而覺得佢大力左, 幾好收.
低唔低真係已經無比較.

巨龍已甦醒了. 上山真係好勁, 回復當年力量.

Yes according to workshop manual, the master cylinder diameter is different. 20vt is bigger than that of 16vt.
But it seems that the brake servo is the same.... Maybe finding a 20vt master cylinder can solve the problem?

Simon

i.e. 16v turbo, area 387.751mm2
20v turbo, area 445.104mm2
it is a 14.7% increment
but i think, at least 30% increment will be useful in this situation.

Simon

found in Fiat coupe forum
sizes of master cylinder as below:
20vt - 23,812mm diameter
20v - 23,812mm
16v all - 22,225

I think u modifly the push rod is same as u shift up the brake pedal higher, should help a bit for heel and toe, but the force still not smooth.
It happened on mind, I brought a 剎車真空倍力器，it just a metal cylinder with a vacuum gauge, install between engine vac hose to brake servo, the theory that should increase the volume of the brake cylinder. I haven't install it yet, duno it can help or not.

coupeelvin

You're using calipers from 20vt?

Simon

Then is it possible if we reposition the push rod anchorage point, so as to advance the brake sensitivity?

Jason16VT

If I remember right, the master brake cylinder between the 16vt and 20vt are the same size.

Need to investigate for the possibility of fitting a 20v turbo (or Nissan??) master brake cylinder.

Simon

因為個總泵太細, 唔夠咁多油推住四遮鮑魚, 攪到個行程好長先有迫力.
而家個initial bite好差, 好模糊. 未知有幾大力, 不過, 個brake反應唔理想.
個迫力低得好唔舒服, 好低,好難做爭趾.
究竟有無個大D總泵啱位呢?

古惑強

His original seats have completely worn out, so he is going to use my sliding chairs instead!

Why item 3?

Simon

仍有問題:
1.油底掙口有滲漏.
2.迫力好低好低, 可能個鮑魚volume大得濟.
3.準備換力奇對原裝櫈.
4.準備換天窗
