Bendix Metal King Gold

[tykoh]

my bendix metal king gold cost me RM78 with installation... i'm driving iswara...
so far i can feel it is better than the stock pad... but didnt know whether it bite my disc or not.... coz just used few months only...

 

[xtremeleo]

if it does warp ur discs, then u'd see it by now tykoh :)

xtremeleo , how exactly do we check if it warps the discs?

xtremeleo , how exactly do we check if it warps the discs?

u can either see or feel grooves on ur discs, the discs r supposed to be flat on the surface. if there r "channels" on it, dat is one kinda warp. basically, discs warp is uneven surface on the disc

FYI, maximum breaking can be obtained if maximum contact between pads and discs occurs. dis doesnt mean dat if the disc seems warp, dat it doesnt bite. as long as the pads fills in every gap / channel on the discs, den u r supposed to get good grip. the thing wit warped disc is, when u change to new pads witout skimming the discs first (means, new pads coupled wit uneven disc surface, which will decrease the contact area between those two items). den, u'll have to wait for d pads to bed in wit the discs and dis may take a while to happen, usually days of driving ur car. u get me bro?

but, wit performance brake pads, such as ferodo and bendix, since they r made outta soft (softer, comparison made between oem and mentioned aftermarket pads) compound, they usually bites faster even when coupled wit a warp / worn discs. they generally worn out faster den oem pads, but consider dis.. it may take years for them to wear out. for me, dats worth all the trouble and sultans spent, as iam not gonna compromise on safety. cheers!!:cyclops:

i see i see... tnx for the explaination dude!! (that was an explaination i couldn't get from the caburetor section) .. lol .. :regular_smile: No wonder now my discs are having grooves ... like, lines. Cause' when i changed my pads to StopTech brake pads i did not skim the discs...

So what do u suggest I do now for my pads/disc? ... Is it too late to skim the discs already?
Or shud i juz let it be until the next time i change my pads then only skim the discs?

The first few weeks/months i felt the braking alot better after changing to the StopTech brake pads... But then after that the braking wasn't that good anymore, so i thought maybe its cause' i have gotten used to it or maybe my pads weren't so "new" anymore..... So now I know that its coz of the grooves that's why my pads arent biting so evenly on the discs! (Am I right?) ... Damn, i didn't know that we have to skim the disc after changing brake pads... But wun skimming the disc make the disc more fragile?

Hope u can give me some suggestions bro... Cheers!! :cyclops:

Bro, thats not warp that u are explaining man.. thats pad groove ler.. disc is warp when ur disc "bengkok", usually happen after sudden cooling of the disc like going into water puddle in rain when ur disc is super hot, not having grooves.. disc is warp when u can feel ur pedal judder (donno if this is the right word), the feeling that ur pedal moving up adn down due to warped disc..

these grooves have effect, as u all may know that metal will expand when heated.. when ur disc is hot, the groove will be offset from the pad thus contact less oledi leading to something like fading effect..

 

[xtremeleo]

from the manufacturer, the discs have tolerence to what width (usually stated in mm on the disc) they perform best, minimumly, witout compromising safety ie discs cracks. u have to look carefully around ur disc bro to confirm what is the minimum width for ur set. if u r using the disc ABOVE the minimum width, then its good to use.

as for me, i didnt skim my discs set when changing to my current bendix set. it bites from the first time i drove wit the set fitted in, and still bites hard now. no, doubt dat other more expensive brand such as ferodo and EBC bites harder, but wit the price i got for my set, iam happy wit it. braking from 180~70kmh is no biggy, everytime. take note, dis is the performance i get wit a 1.3liter turbo motor, wit a 800+kg car. dont expect the same performance when u fit dis set in say.. a supra, or a heavier car

get d right set for ur car, i dont think u need bendix metal king gold (now, there is the plus edition, bites even harder. i dont necessarily need dis set, but wud be a good invesment for safety purposes), maybe u shud try the new bendix set, titanium strip. wit dis set, u dont need to skim u discs when changing pads. i can get a very good price for dis set(s), just gimme a call when u need assistance on the weekend (mostly satrudays, sundays r for family. hoho..) 0163571811, cheers

i think u r rite, i apologise for d mistakes i ve made guys. but what i was trying to explain is about the un-even-ness of the discs, which is the factor to get a good breaking grip. i was confuse between the correct word (either warp or groove) to use, dat was y mentioned "dat is one kinda warp. basically, discs warp is uneven surface on the disc", which shud cover both scenarios. shud have used the correct word, to avoid confusion between us forumers.

thank you tajulsan for pointing my mistake out:_:

judder is the right word imo, as u can feel its shake when breaking, ya? its like the pads r biting on uneven surface, ya? but, can u explain a lil bit more on ur last prara? i dont quite get it, less contact fades discs? disc hot, and groove becomes offset?

 

[tajulsans]

ok, since ur disc have groove line, the pads have matching line on it right?? when metal heat up, it will expand right.. the disc will expand outward ie. the disc will increase in diameter, due to this, the groove line on the disc will also be offset outward while the line on the pad stay where it is thus leading to line unmatch & less contact space.. this will lead to reduced braking performace, thats why it is advisable to skim ur disc (if grooved la) when changing pads..

 

[nitrus]

Ok.... So it still comes down to the same thing for my problem, my brake pads are not biting properly on my discs coz of the grooves/lines on the disc ...

So FOR NOW, does that mean i have to just skim the discs to get back my brake pad's performance, OR skim the discs n change new brake pads to restore my brake's performance?

Plz advise.. Tnx...

[xtremeleo]

good explaination tajulsan, but one thing still plays in my mind rite now. the way u r saying, as if heat doesnt affect or has lil effect on the pads. they r metallic, rnt they?

[tajulsans]

Wah khoyos, wanna ask us to use carbon rotors ka?? hahahah..

bro, the pads is metallic = metal compund, not metal 100%, there for expension is not proportional to iron right.. plus the pads are not restrained from expanding.. the rotors are restrained at center..

 

[xtremeleo]

nitrus, i'd go for ur 2nd option. its the best way to be sure

 

[xtorm]

haih.......guest i was chop, pay rm180 for metal king gold included installation.....but mine is a suzuki swift old type, abit hard to find.

bite was supprissingly good, but i heard ferodo is pretty good too, my friend using on his iswara, not bad at all, but i nvr drive his car b4, so no idea

FOR NOW, just use the pads as it is la.. no point to skim now as the pads already have groove ler.. u skim ur disc and reuse the pad then the same problem repeat itself lo.. Next change of pad oni u skim ur disc.. btw, problem with groove disc giving fading effect onli occur at high temperature, normal usage will not effect that much ler..

 

[nitrus]

Thanks xtremeleo n Tajulsans .... I think i'll juz leave it be first la, next time only skim n change brake pads... ehehehhe i baru change this brake pads only... tnx guys! Much appreciated :regular_smile: cheers..

 

[nitrus]

One more thing ... Do u guys have any recommendation of shops around PJ that can do disc skimming for a reasonable price? Around how much will it cost..? tnxx

 

[xtremeleo]

i think any machine shop can do dis kinda simple job, or sumone dat has a milling machine (tajul, iam confuse about the machine name again, do correct me k). last time i did for my fren's GTti, it cost about RM15 per piece. the shop is in setapak
