i think the main advantage of performance rotors r they r able to withstand high temperature without failin...but expensive. n dont think they have it for all cars.

just like racing pads, even if u trash them, they will work. but if normal pads, the temp is lower than racing pads. so they r easily overheat if u trash them n they will fail to perform normally

hmm okay
i think i might try the peformance rotors if they aren't tooo exp lol :D
thanks ong for the info :D keke
so hows the titan going?

A33 Rotor original @ RM 350 each.

A33 Rotor original @ RM 350 each.

thanks for the info :D
jsut wondering will there be any side effects if i leave it as it is?
or there'll be some chain reaction??
cause m pretty bz recently :S

 

[dream.tent]

Just don't drive too fast bro!

 

[0123]

hmm i try le :D

 

[weikee]

disc warp are due to many factor, and personally have encounter few reason for the disc warp,

01) bad quality brake pad.. i used one so called expensive pad, and it warp 2 set of my disc, than later decide to change the pad, and skim the disc... and working fine.

02) due to heat dissipation very bad.. used to drive a sentra B13 with upgrade disc and caliper. with the standard rims, i always have my disc warp, and change every 6 months.. later change to bigger rims no problem.

03) heated disc after usage and cool by water.. usually happen when you send your car to wash.. <yet to try, but its common for normal users>


RM 350 per disc, if can change to 4 pot nissan brake lah :D

 

[ongteckweng]

agree with weikee...now i learned more...
anyway, changin to 4-pot might not be a good idea as we have discussed b4 during our last TT.

our brake pump is not big enough n they might have hard time with d 4pot. if u wanna change to 4pot, consider the brake pump n brake line as well

 

[weikee]

Hi Ong,

for the brake pump, can always used the R33, or any nissan master pump with 1" size. Think the minimal is 15/16" but you can check it out in the chop shop they have lots of master pump for nissan with various size stamp on the brake pump. just take one that are higher than current one and the hose run the same way.

Used to upgrade my sentra with the twin pot and master pump... brake today stop yesterday :)

now with fatty, brake today stop tomolo... need to upgrade soon

 

[0123]

aiks i also duno what to do what weikee's idea sounds good haha.
but how much you recon it will cost to change them O.o" disc & 4 pot caliper
and also the pump n line??

 

[dream.tent]

But our Feilo with Electronic Brake Assisted, how to go about? can change the master pump?
If so, maybe it's a good idea to just folklift the master pump and 4 pot brakes. brake lines not too expensive! good to have them too!

 

[defcon1]

i would first explore changing the master pump. My Celica before had only twin pot calipers and weighed 1.54 MT (1.55 with me in it)...but managed to stop much faster than the feilo.

Let me ask Lee and see what we can work out...

Also, you might consider steel braided hose and dot 5 or 6 brake fluid as a fast and effective upgrade. You will find that your braking performance improves by at least 10% - 15%, which is a lot...

 

[weikee]

hi Defcon,

brake steel braided hose actually don't improve the braking performance, but will reduce the spongy feel. I used to have one set in my old sentra.. and this things don't last longer than the OEM hose.. the dam hose leak, and i lost brake.. wramp into a few months old 5 series.. gosh... that was bad... lucky i was traveling slow and damage are not too bad. So when used steel braided.. please change every 2 to 3 years.

For 4 pots, you can try the silvia S14, or S15 its smaller compare to the skyline. Think someone in this forum selling it around 400 +-. For skyline 4 pots, my last purchase nearly 2 years ago are 500 for complete front and back, front its normally rm 300 ++. Now maybe 400+-

If not mistaken the A33 EBD control by the ABS pump just like the N16, and P11 SR20ve. My friend upgraded the P11 sr20ve 4 pots and n16 (to twin pot, rear cefiro) its working and actually its perform better cause its distributed very well for the N16.

I am planing to put in 4 pots once i full done out my engine, and change to 16 or 17" rims

 

[defcon1]

Braking is actually a function of pressure and time. "Reducing the spongy feel" by using steel braided brakes lines and using higher dot rating fluid basically means reducing the time taken for the brake system to reach maximum braking pressure. This happens because :

a) The rubber/teflon hose inside the steel braid has only the confined space inside the steel braid to expand when brakes are applied.

b) Higher dot rating hydraulic fluid has a lower compression capacity, again reducing the time taken for max pressure to be achieved.

Whether they last longer or not, depends on the quality of the brake line installed. Technically, these are supposed to be high pressure hydraulic lines, and if properly made, will generally last years. My Goodridge set lasted me 5 years until I was forced to get rid of the car in Sg without a leak. The ones under my car now, are locally made, but have yet to start leaking.

You are right that 4-pot calipers should work better by DISTRIBUTING the force over a larger surface area. BUT, the amount of force remains the same, simply distributed over a larger area. The question is...is it really necessary? A combination of good response time, plus good brake pads should suffice for most people here.

A direct way of increasing braking efficiency without major surgery is to increase the clamping pressure of the existing brake calipers. But this has to be done carefully, or you'll actually start to leak...

And I haven't even started on the material and design of the disk yet...

 

[weikee]

my 2cents, braking performance are base on few factor, clamping force, clamping area, material, distance between caliper to the center point of the disk. Any of this increase will give better braking result.

thats the brand i was using, and it give way after 3 years.. well maybe i clock to high mileage already..not too sure about the improvement of normal to steel hose, never really feel and major drop in the braking power when i change it back to normal hose.

the 4 pots in the a33 should do better comparing the a32. it got ebd and should be able to distribute the force better. just like my friend ex-20ve we used to drive.

Actually i am a brake fanatic and spend quite a bit of money on brake for my previous sentra. from normal vacuum pump to big pump, to larger master pump and to caliper & disc from single to 4 pots.. you name it i change it.. even CNC fabricated a mount to make a 4 pots and 2 pots for bigger disc..and end of the day, the hose that kill my braking power..sigh

Oh, btw, do change brake oil regular, cause contaminated oil will kill the ABS pump fast. I flush every 12+- months.

 

[dream.tent]

So far i don't practice change brake fluids. But when it gets dirty and no longer looks clear, i'll have them flushed. Using Dot 4 all the while. Even with my Feilo now. Didn't see Dot 5/6 around actually! need to special order?
