Rear brake squeaking

[KM85]

I ride a Honda CBF 125 (62 Plate) and over the past week ive realised that the Rear brake was squeaking when pressing it lightly. This morning I noticed that the front brake done the same!

What can I do to fix this? As it is very irritating. I know not to use WD40 on it so any other help would be great.

Thanks in advance.

I have an '11 plate CBF - I get the same thing first thing in a morning (kept outside), but it disappears after I have gone around two corners (slowing down to take them). Does yours stay on for your entire trip, or does it clear up pretty soon?

Yeah it usually in the morning and then when I'm on it for about 5-10 minutes then its usually ok?

Same when going home from work as well.

I'm gonna keep an eye on this. When I gave the bike a good clean, that helped a bit but came back. TBF, I have earphones in when i am on the bike, so it doesnt bother me a lot, but I wouldnt mind putting it right.

That's yeah I was looking about and seeing if there was any lubes I can put on the brakes, but I'm not sure if rubbing stuff like that on the brakes would help.

do you need new pads ?

[KM85]

Vincent - I was gonna give it a little clean when I get home. It's been pissing down for a week straight and todays the first dday in a week that I could probably get a look and clean it.

mjn51 - I'm not 100% sure, I'm new to motorbikes and the bike itself is only 2 years old wwith about 1700 miles on it.

As well as s checking the general condition of your pads, I would make sure that the caliper piston(s) is clean and moves freely and the same with the caliper slider pins (assuming you have them).

I'm another one... I have a 2013 CBF and if there's been rain my rear brake squeaks for a couple of hundred yards of travelling.

I'll have a look at what you've said Busa, cheers. For Hondas CBFs really do seem shite.

They normally squeel when the pads are low. It's an indicator for the rider to get them changed. First port of call is to check every pad.

Squeeling after it has rained is fairly common. Rain can leave a lot of shit on your discs, so if it stops after a little while it's because any crap left on the surface of the disc gets burned off.

The other solution which would need doing, as mentioned before, is copper grease on the back of the pads. You only need to put a bit around the area the piston touches to prevent the squeeling. A clean piston/free moving piston and clean/greased slider pins are something that needs doing, also.

It's probably just a little surface rust on the edges of the pads.which goes away after a little bit of braking

[UrbanRacer]

I used to get it sometimes on the S1000RR, To get rid of it i used to get up to a decent speed and then brake hard. It was enough to take it away for a while.
If you intend on doing this be careful, the cold gritted roads at this time of year don't offer much in the way of grip.

Use vaseline to stop the pads from moving around/vibrating = squeaking.

My front brake squeaks, the pads are nearly done (1.5mm left), so they move quite a lot, but I kind of like the sound of the brake, when you make full stop with the very notable squeak.

Careful with abrasives on your pads, they can pick up the abrasives and then scour your disks.

Check pads have not exceeded wear limit. Your pads are composed of a friction material and a back plate. There are often wear limit grooves in the pads but not always, less than 2mm of remaining friction material means you should probably change pads.

Carefully clean the caliper and the back plates of your pads with brake cleaner and a rag. Do not get grease on the friction material. Apply copper grease to the backs of the back plates where they touch calliper or piston, and very very carefully apply coper grease to the edges of the backing plates where they slide in the caliper. Also do this to pad retaining pins if there is one. If you have a sliding pillar type caliper check the calliper is free to move and again carefully and sparingly apply copper grease as required. Do not use anything other than copper grease or high temperature brake grease if specified in owners/service manual. Regular greases may melt and spatter oil on your friction surfaces which is kind of bad.

Clean disk with brake cleaner and a fresh shop towel or clean rag.

Organic pads are noisy, sintered hh pads can be noisy. As its your rear on a 125, you shouldn't need a hh sintered pad, if its really bothering you try a carbon ceramic pad, low dust, low noise, nice and smooth for trailing some rear brake and predictable in the rain. Cheap too.
