So how does the braking feel now, any significant improvement compared to your previous brake setup?
Last time my friend converted his Nissan Bluebird brakes to GTR ones, did not improve, in fact got worse, because vacuum servo cannot handle, until he added aftermarket (add on) vacuum servo

Honestly the past few months I was quite lazy and did not get the chance to do any testing wasn't able to compared. But i notice one difference at low speed around 60kmh i slammed the pedal and it did not took long before my car stopped

Does it come with bigger vacuum servo?
When i bought my car it comes with a 96 dc2r brake servo. Hope thats good enough

i think i borrow this thread to ask. Keep playing in my mind.
I ask before about brake pads.

My case. Wira gsrt, no mods, stock (all disc brake, single port). Brake been bleed couple of times. After bleed feel much better.
Few weeks later, pressing the brake pedal. Back to same old feeling, not much braking power. Press 2-3 time only can feel the hard feeling. Brake pads not worn out. No hydraulic oil leaked.

Need advice. Problem at Brake hose ? Brake caliper becos single port ? Brake pads ? Brake servo ?

If you need to press 2 to 3 times to brakes to function properly, usually means got air bubble in the system and needs bleeding.
For better braking try changing the pads first. Try Trestor Blue Advantage pads, cheap and good bite, but a lot of dust......lol:biggrin:

Okay noted. Will keep that in mind... when i ask around, my friends told me can use ek9's servo but any other suggestion?
Before changing make sure the servo unit is bigger, but then also make sure got space for bigger unit to go it. Mine was transferred from half cut, unit is bigger and is double layer

Rubber hose can have this effect ?:confused:

Does the brake pedal sink when you hold it there? If it does you might wanna have a look at your brake pump too the seals and all. If it doesn't probably like what sifu vr said, bubble inside. Just my 2cents. :burnout::burnout::burnout:

Normally if worn and pedals sinks, I rather change the pump. Most pumps nowadays are made of aluminum and they are soft and wears easily. The seals wears the pump wall will wear also. I did once changing the seals only lasted a few months.....lol

How the windscreen, yesterday got rain, right?

Brake pedal din sink, just feel need to press further compare to after bleed.
Bleed couple of times previously. Wondering where the air come from.
Or pump itself suck air by little?

You just bleed or flush? I recommend you do a complete flush, means change the brake fluid completely. Also did you overheat your brakes at any time after the bleed?

Duno about overheat uncle VR.
After bleed each time, drive normal like usual.
Just slight pressure will do. After few weeks...loss that feel d.
Will do full flush if can help.

Can try adjust the brake pedal free play, that can help if your free play still a bit much. If already minimal then cannot. Changing brake hose with stainless braided ones also would help firm up the pedal feel a bit.

What brake fluids you use now? If still DOT3 then upgrade to DOT4 better.

How do you guys test your brakes? in terms of "bite"ness? Drive to 120 then sudden brake to 60?
I do think like I need to bleed my brakes... Cause i stepped 1-2cm into the pedal still did not feel like it's biting unless i step further down..
