thinking about it, why does rear tire tend to skid ah? they are bigger then the front one what?

 

is it because of the weight throw forward thing when we're braking so the rear tire 'lighter'?

 

yup you're right!

The dynamic weight transfer shifts more weight to the front tires thereby loading it up and hence the front tire gets more tractive force for braking.

At the rear, the weight shifts away from it so it has less force acting downwards and so it's less likely to hold the ground.

 

You can actually reduce the chance of locking up the rear tires under braking by having more static weight on the rear tire; more stuff in the box, more preload on the spring, lowering of rear ride height. But I think Honda would have done a proper job to check the bike's balance. So better not mess too much with it.

i always thought having more stuff in the box, ie heavier rear would cause fishtailing due to locked rear wheel to occur more often..

I had the same weak-rear-brake prob till recent I change to EBC pads. Before the rear was like totally no-brake and that very sticky feel as though it goes in stages. After the EBC pads went in, all these problems were solved! It is not the discs here. Even the original pads don't work. Now the rear wheels will lock if only I slam with my right foot, otherwise it's what I call "that's-the-way-a-brake-should-work!"

 

PS: EBC pads are not cheap thou.

how much? anyways it sounds interesting, if i can know the price, so why not change uh

[khaitronic]

just got s4 today...true enuff it braking really let me down...compare to my rg.....thanks to this thread...at least now i know its a common probs face by all

Price is $70.

[Guest snowdog]

oh ya... btw wrt the 70% & 30% braking forces... If the rear brakes don't work or it is weak, it is = to 100% braking force in front & 0% behind which will not balance the braking forces which is 70/30. Balance braling force is important, that's why now most new cars now got EBD to balance the front & the rear braking forces.

I've been riding my s4 for years, and personally, I find the braking sucks. I have changed to EBC brake pads, Hel brake hose and yet am still not satisfied with the braking power, especially the front because I seldom use the rear excpet to tap it in the corners. My next move is to buy a brembo master brake pump for the front to improve braking.

 

Braking is personal, some like it hard, some like it soft. There is no hard and fast rule about it.

time to service your brake calipers?

[dingjc]

servicing calipers? wad do they do to it actually ar ?

servicing calipers means, dismantling it.. giving it a good wash and scrub down.. replacing the rubber O rings with new ones, and clean up the pistons(change new ones if necessary)..

 

price for just changing the O rings would be abt $100plus..

I suggest u dun dismissed it as jus a common problem, cos urs and other may not be the same problem afterall. Best to confirm with a qualified mechanic.

 

Just for sharing.

how come no one wanna try the easy n cheaper alternative by spraying oil at the rear brake pump? i dunno how to explain but it does help. BUT if the brake pump is detiorating, then no matter how much oil sprayed will b useless. in that case, change brake pump is the option.

[dingjc]

spray with wad oil? wd40? u was toking spraying at which part? the disc plate there or ? cos i dunno wad u meant by break pump there. haha.

any oil will do. wd40, chain lube, gt85 all can. spray at the brake pump. its situated between the right foot rest n swing arm. brake pump brand is nissi. at the lowest part of the brake pump, it is rubber. spray oil inside the rubber will do.

 

sometimes when its hard to control the braking force for the front, the mech oso spray oil to solve this prob. same goes to the rear.

 

hope it helps...

Try to avoid WD40 or GT85. They promote rust because the stuff doesnt hold on to material you're applying to. After they are gone from the material, it's exposed and can rust pretty fast.

By right you need silicone grease (whitish substance meant for contact).

Nah, it's just that i've found the front brake caliper too soft for my liking all these years, gonna save up $ and buy a brembo master brake pump for street version.

My dad bike: super4 version s

problem : front brake sometimes lock and need to brake again to release

 

he send to famous bt merah shop there, told him not to but he insist, as near to home..

 

he mechanic say need to change brake pump and service caliper..

 

total $170 gone... i still believe no need change brake pump, just service the caliper alone is enough...

[dingjc]

how much does servicing caliper cost ar ? (:

[arsonist]

can anyone share with me what brakes are good that u are using?

cheap ard the 20 dollars range but acceptable performance?

also can pls tell me where u buy it?

 

i need to change my frt brakepads la

thanks in advance

[PaLmEr]

I'm using EBC HH rated pads. Expensive @ S$65 or so per caliper but stops on a dime.

[arsonist]

u bought at unoque issit? i read the s4 components pricelist that lab selling ebc hh for 45? and bikelab sell for 35? is it true?

 

if not true then i'll try to get a bit cheaper ones ar, cos no budget ar this month.

 

does anyone knw how much are braking brakepads? last time uberstore got sell ryte?

[Mussolini]

u go for WP brakepads. cheap n good but need to clean the brake dust once a while

[-Imran-]

Change front brake pump : $120

Service front brake caliper : $50

[JuZ_FZ6]

it also depends on where the cailiper is placed. If the cailiper is above the swingarm, it is slightly better than the one below. Such example is PB1, Ver S & R etc. for spec i not so sure. even if my rotor is un-even, my braking power is still tops, in fact better. But the pad will go faster. then i change to wave rotor... super power...
