I have never really felt the rear brake being effective. It almost feels the same.

Does this means that you don't get any braking performance from rear brake ?
DO you use only front brake? or you use it as a combo ?

WD40 is a water displacing lubricant containing oil . No , it is not possible to clean the pads to regain full braking effect . I have no idea of the cost , you'll have to ask yamaha service center about that . Aftermarket brake pads are also available . But whatever - it shall be less expensive than riding around with compromised brakes

I was doing the month (per 500 km) maintenance yesterday. Used WD-40 for cheain clean, then i saw rust on the front disc plate , so i sprayed WD-40 on the front and rear disc brakes , how intelligent of me i know

. Then i left it for 15-20 mins. Traveled around 10kms to drop someone, on the way my cousin almost bumped it in to a car, i cursed him (slowly), but he was driving really slow and is very responsible, then on way back to home, i almost bumped it too. Then i realized my ride had almost no brakes

. Took it for presser washing. Came back home, lubed chain , polish etc. Then after 2-3 hours took it for a spin, again no brakes. Then though of coming to office today on bike, NO BRAKES. OMG , someone actually commented on me drive faster.
Please someone tell me wt actually happened and wt needs to be done to fix. Because brakes is the most impressive part about this bike and i was so proud of them, now i am only proud of my stupidty

.

Mr. pinaki is right. you have put oil on the disc, and that oil is got absorbed by the disc pads. now nice .lol. change the pads. dont do it again. if you are comparing it with the brake oil then think again

the disc pads may cost around 1.2k

Either you are judging it wrong or your ride needs to be checked at SVC thoroughly !!

R15's braking and tyres are best in india, apart from some big competitors.

Both brakes used as a comby is much effective to bring R15 from 130+kmph to 40-60kmph instantly.
I would suggest you to get it check.

Rear brake is also as imp as Front is. Do not ignore this symptoms.

**Pinaki** · 04-15-2013, 02:41 PM

Get the service to check your brake system for faults and minor adjustments . You can fit KBX brand pads which are of asbestos type , lots cheaper , wears out faster (wears the disc slower) and gives better braking . Worth a try . Scrub clean both the discs with scrotchbrite+detergent+water throughly and dry em before you fit the new pads . Never get anything oily, greasy or slippery near them - they work by friction .

**himanshunegi1987** · 04-15-2013, 03:13 PM

If i buy a brake cleaner and spray it over the disc , any idea if that should help ?

Can i remove disc pad on my own, with the default tools provided ?

LMAO!! yea i meant other category of nuts as TeeJayy said

(in other words Guts!!) And today topped up the coolant and will check for any drop in level.. Strangely today i heard 3 misfires but i seriously don't know whether its from my bike.. 3 times that makes me think its from my bike maybe

..If its from mine,it is the symptom of blown head gasket and coolant leaking into engine oil bay right??

Edit: Mostly my head gasket is blown.. I checked the oil through dip stick and it feels different and bit watery too

Any other ways to find whether coolant is leaking into engine oil bay? Will ride for 2 days and check the level of coolant though. And is changing head gasket pain taking task? I mean will it take time? (For SVC, No DIY) oh god why is this happening only to me... F****** sad

Cheers

My friend wanted a new bike, and was continuously asking everyone about the best bike to buy until he saw me and test rode my bike

Blue is mine

Yes , that shall help the disc (steel) but not the pads . The pads are made of porous material and has absorbed the oil . Try to replace them . OE pads are non-asbestos type (near back colour surfaces) . If you are hesitating for the cost of them , try to find asbestos type (khaki/borwnish colour surface) KBX brand aftermarket pads for your R15 which are cheaper . A cleaned disc and new pads(any type) shall restore your braking now .
Yes , of course you can change them yourself - and learn about your braking system in the process . It's quite simple really . Even if you mess up, you can always show up at the YASS with a sheepish smile and pay them to fix it - no harm done . Read this link and ask other R15 owners for more precise guidance and help (I don't have an R15) . http://www.xbhp.com/talkies/do-yours...replacing.html

what do u mean u are not sure if its from your bike! that misfire could be caused due to bad fuel or spark plug. If your head gasket is blown you will find oil stains around that area!
And i don't think you are good enough to judge engine oil by feel. Is the oil level down ?
Like i said, check regularly over a period (a week or a month) for drop in the fluid levels.

and first try to take out as much petrol as possible from the tank and fill up from a 'reputable' bunk.

I fill always in shell buddy and misfire( first am not sure whether its from mine or someone else's bike in traffic) is not due to fuel or spark plug.. I heard if coolant goes into engine oil bay it comes out through exhaust as pressurised steam which sounds like misfire. Oil level is fine.. I feel like it increased due to this problem and what area did you mention?? I mean where can i find oil stains if head gasket is blown?? Ill monitor the coolant level this week and report.. Thanks for your help

**stefanm** · 04-16-2013, 12:21 AM

^^ Have you seen any white smoke from your exhaust? when you checked your dip stick was there any milky residue? These are tell tail signs of a blown head gasket, you can also check your spark plug for any coolant residue and check around the head for any bubbling, a simple thing you can do with any mechanic is to drain your oil, if there is any coolant at the surface of the drained oil, then you have a buggered gasket, if not then you can pop the oil back in. To me your symptoms sound like you spark plug cap maybe faulty, it's a part that goes bad quite often on this bike, mine had first gone bad at around 3.5k kms and again at 10k kms. Changing the head gasket is not such a big job if necessary, only you will need coolant along with the gasket.

Oh yeah, try not to use the bike until you find and solve the problem.
