hi bros, just checking whether any bros have experience this when travelling at high speed like 160kmph and above and you do major braking (not ebrake or jam brake) but some serious braking to stop the car, the car seem like shaking and falling apart. but eventually will stop still. dunno whether is due to stock brake or disc plate problem that might have causes this. Appreciate any views or experience on this. PS: mine is V1 with only front disc.

shaking? the whole car like vibrating like travelling over rough road and you feel the brake pedal shivering like pushing your foot back and releasing in a very quick manner?
If yes, I think it's the ABS kicking in. Though I cannot be 100% sure if you understood what I am describing

Hi bro... i know yr problem... i had it once... wat i did was to do all the wheel related stuff and most impt is high speed balancing done at next to vim auto... hope this helps...

Seems like ABS..

feel vibration on steering when you brake? your rotors may need skimming or replacement...

V1 no ABS lah.. only front disc rear drum..
Jam brake at 160km? i don't think anyone do that over here..
So far when try to slow down from 140km no problem.. Maybe need to balance the wheel.. Y not do at Citytyre, same time can alginin your wheel,

Oh yeah..V1 first batch no ABS (disc/ drum), V1 later batch got ABS (disc/disc)...

yap bros. not abs. cause mine old model. not steering wheel shaking only but rather the whole car is shaking. dunno whether is the disc or rotor problem. wheel not likely cause quite smooth and steering also not much vibration during high speed crusing. its only when travelling at 160kmph on NSHW then stupid coach bus or truck cut into my lane i have to do some serious braking then viration throughout the whole vehicle can be feel. like for that particlular moment the earth is shaking. could it be brake pad as well or our braking system not able to handle serious braking during high speed?

I also encounter that... But braking at speeds more than 120kmh... Maybe the rotors are warped or pads uneven wear...

warped rotors are quite easy to detect (in most cases), the brake pedals will have this 'feedback' sensation like ABS is on even at relatively low speeds.

Confirmed brake rotors need skimming as they had warped...had it on my previous ride before,a skim on the front rotors will solve yr probs..tk tis opportunity to chg to slotted/cross-drilled rotors if u hv tat xtra bit of moola!Braking is as equally important! Rem not to spray direct water onto the rotors when the rotors are hot after a hot drive!It'll accelerate the warping of the rotors and cause problems to your braking!

Is the process of shaving off the surface to get back the flat surface called skimming?.. ...Juz wondering, will it affect the performance of the rotors as it will be slightly thinner? ....If my rotors were to have problems, will consider changing to slotted rotors rather than change back to stock rotors....

bro u mind explaining or give more detail on tis 'feedback'? n is d rotors u talking abt refers to disc brake or rotor brake? sori for my stupidness bro.. no prob. the 'feedback' sensation is like the brake pedal will push back upwards against your foot. eg: you put your hand on the window and someone knock on the other side, your hand will get this 'feedback' sensation. When ABS is activated, will also get this sensation. rotor refers to the what commonly ppl call the brake disc. Both mean the same thing. I think rotor is either a technical term or slang from US. Skimming willing fix the problem for now, as there might be other underlying reasons to why the discs had warpped (if they are warped) in the first place. Using lousy quality brake pads will cause this warp sensation also because the pads deposit the materials onto the rotors when extremely hot. Skimming can solve this problem also. psyfool: skimming is the process of 'cutting' away the top layer of the discs, some call it "resurfacing" also. Do ask the workshop to check the thickness of the rotors you have left before skimming, some might just blindly skim for you because you said so and leave you with a dangerously thin rotor

anyone know where can i do this skimming? my car warranty ending soon. can i go back cnc for skimming? what brake pad is recommended to use to prevent the rotor from being too hot and wrapped? any ways to prevent wrapping of the rotor? hope someone can clear my doubts

Best is to revert to aftermarket high temp brake discs(rotors)+same temp brake pads for utmost suitability!

Upgrading to stainless steel brake hose only improves the "feel" of your braking when u depress on the brake pedal. Dot 4 fluid will only withstand higher temperature than Dot 3 fluid or lesser in the brakeline. Latest Dot 5.1 brake fluid in the market now which can withstand higher temperatures in the brakeline than Dot 4 which is quite the norm now. Both the above-mentioned has nothing to do with brake disc (rotors) warped.

I doubt C&C will offer any skimming service..they will surely straightaway say change to new rotors...especially after warranty over..chop & chop... Steel braided hose reduces the ballooning effect under hard braking..so when u depress the brake, the full pressure can be transferred to the pistons effectively...but i tink if for normal driving, the effect is not really significant..Exzess got for Cerato..saw at Autobacs..
