Rear brake on NSR 125 help...

[Blunet600]

My rear brake is shit! it hardly does anything when pressed down, i have to use the fron brake for everything as th back is nor reliable. how can i change this or what might be the problem?
i have topped up the brake fluid in case it was that, no change, i have tried altering the position of the rear brake lever, no change. please help?

[veeeffarr]

Have you tried bleeding the brake system?

Do they feel spongy?

[Blunet600]

i havent felt them spungy? but i know i have to push really hard on the lever to get the back brake to have some (little but some) effect on the slowing down of the bike.
i havent tried bleeding it no, i didnt think i woudl need to coz i dont think it is this. how ever u could be wrong.

The rear brake on any sports bikes are crap, mine is poor, thats why there's a massive front disc.

Front brake is fine to use alone.

Top up your brake fluid and bleed it as you go.

If it still feels the same after then you may need new pads, they're a piece of piss to change. While you're changing them give the Caliper a good srub and clean aswell and check the condition of your brake disc while you're at it.

If you need to change them give David Silver Spares a ring.

And if you feel up to it while you are doing the back give the front a check and clean.

Mine is useless as well, just make sure you look after the front brake.

rear break on nsr is just a slow down accessory . it's good that it's not a strong one , otherwise you had fell down very often ! you can improve a bit by changind the rubber pipe between the master & caliper with aeroplane type (brembo) .

buy how does your bike passes the mot? i mean i just spent like 2 weeks trying 2 get my back brake on my rieju 2 brake from new pads 2 new spacers 2 cleaning my back disk and wearing my pads down and its slows the bike down but i am takeing it for an mot 2moro, but at the otherhand your back brake shouldnt be sharp coz it lock up and i did that once with my old yam and i nearly flew off the bike

The back brake on my NSR is actually quite good, you only need to use it lightly, otherwise you could lock the rear wheel. There's certainly no need to "push really hard on the lever" with mine.

The rear brake on my scoot was like that... I changed the pads, gave the caliper a good stripdown/clean (found out one piston had semi seized) and then finally gave the disc a clean with some ethenol to make sure no oil/grime were on the discs (which might be your problem). Now I can lock the back wheel quite easily if I want. Before I nearly could pull off with the lever in as far as I could pull it!

You can pass an MOT with a fairly weak brake (not as in lever to the handlebars just generally shite) since they only take it off the center stand and push the bike forward while grabbing the brake. Mine would grip ok if I was just pushing the scoot around... Was worse than useless at anything above 10-15mph though..

I remember actually back when my rear hose needed replacing.. I took my scoot to the bikeshop with a crappy rear brake and it came back exactly the same. I was hoping they'd sort it but they must of assumed they were ok but just pushing the bike around you wouldnt've known. but yeh 3 days later all the fluid had leaked out causing complete failure fucking idiots. Didnt think to double check all the bolts were tight when they replaced the hose had they!! shouldve went back and kicked off but you cant exactly prove anything
