Changing Break Pads,

Well-known member
So I have clocked 17K on my 08 CBR 125R, Checked the front break pads and realized they are toast. Bought a new set and was going to change them my self this weekend and was wondering is this a difficult process? I do my own oil changes, I changed my horn, and I do chain and sprocket maintenance by my self so I figured why not give it a go.

Anything I should be careful of, special tools my kits might not have, tips or tricks? The dealership quoted me 30-45 minutes to do it so hopefully it will not take me much longer.

Any help/ advice would be great. Also, the pads came with a small info pamphlet but it only mentions to check the break fluid and to see owners manual, which I no longer have because my dealership lost it on me over winter storage . :-/ [if anyone has a download of the manual for my bike, that would be great.]

Thanks,
 
its a simple process actually. Not sure what the 08 125R calipers are like, but the tokico calipers on the 08 1000RR are dead simple. I'd suggest getting the service manual for your bike, it will make tasks like this much easier, but here is what I do:

1.) remove the 2 x 14mm bolts holding the caliper into the fork
2.) pull off caliper, your not supposed to let them hang by the hoses, but I do (SS lines, probably wouldn't do this with the stock rubber ones)
3.) make sure there is some room left in your brake fluid resevoir, i.e. it is not "full", or its going to spill when you push the pistons back in, and cleaning up brake fluid is a pain. If you do need to clean up brake fluid, use isopropyl alcohol ($2 at shoppers).
4.) using a flat head screw driver, seperate the pads, all the way out. On the 1000RR I use 2 hands and 4 fingers to get the calipers all the way out, since you need to push all of the pistons at the same time.
5.) remove pads. In my case its 2 pins in the caliper, pull them out, brake pads fall out.
6.) this is a good time to clean the pistons if you want. Kerosene is my favorite, but gas, varsol, etc. all work with a q-tip. If you decide to clean up the entire caliper/pistons, push the pistons back out using the brake lever. Be very careful not to push the pistons all the way out, they can be hard to get back in, BE CAREFUL!
7.) insert new pads, keep your fingers off the pads, oil/greese on the pads is bad. To get the pins in (at least on mine) you need to put the pin through the first pad, press down the spring on the butterfly clip that sits inside the caliper, then push the pin through the 2nd pad. It won't go through the 2nd pad otherwise.
8.) Clean the rotor with towel/green scratch pad/(I don't recommend it) steel wool using brake cleaner, scrub it well.
9.) put calipers back on fork mounts around the rotor, put 2 x 14 mm bolts back in
10.) squeeze the brake lever to push the pads into place
11.) seat the pads by Driving around for about 60 km, your brakes are going to feel like they suck, be aware. After 60 km or 2 dozen good stops they should feel fine. The brakes should feel like they are grabbing, just not stopping. If your brakes feel spongy i.e. not grabbing, a lot of travel in the lever, you will need to bleed the master cylinder/calipers. Simple process, just takes a bit of practise.
 
Very detailed, Thank you. I'll let you know how it goes

I'll call my dealer ship and see if they will cover the cost of the newer service manual. [08 manual was discontinued]

When you get the manual keep it in super nice condition and when you're done with it I'll buy it off you and e-mail it to you in PDF.

I will take a look for the manual from my old 08 125r. If I find it I will pm you.

The service manual is more useful than the owners manual, but I'd take either.

Done, Did it last weekend took 20 minutes. Also, Honda e-mailed me an owners manual and it was not very helpful. Now I am hunting for a service manual.

I was actually surprised that there was still some meat left on the old breaks but they felt like they sucked. If I filled the master cylinder back up with the old breaks on would I have more stopping power?

Just wondering.
 
What do you mean "fill it back up"? lol.... if it's low you obviously should. If the fluid level isn't high enough, air can get in the master cylinder/lines when you're turning/leaning.

Not a bad idea to bleed brakes while you're at it too.

Well, I am new at this still. I will get fluid tomorrow and youtube a video on bleeding brakes.

Cheers.
 
If your pads are broken you should look at getting that fixed. Or did you mean brake pads?
 
Something doesn't add up in your posts, Newblet. Usually when your brake pads are almost done, the brake fluid level in the reservoir will be close to minimum, maybe even lower than that. When you install new brake pads, obviously you'll push the calipers further back in, the brake fluid level will go back up. On my CBR600, the level went up from min to max when changed from worn out to brand new brake pads. Do not overfill the brake fluid either, the maximum level is usually very clearly marked.
 
If you're in the Thornhill area, I'd be happy to lend a hand

Sounds logical, I will keep this in mind when I change my brake pads on my 08 cbr125 with 50k. 17k and and pads are worn out? where was this bike ridden or is the op fixing something when it's not broken.
 
I just replaced my brake pads after 50 k on my 08 cbr125. An easy job, all that's needed is an allen key. The job is so easy I should have it done it sooner. Honda wanted $55 a set: proposterous, so I ordered elsewhere. Even with shipping and broker charges I saved $45.

Hrmm, my front pads looked exactly like yours. Maybe I drive a little harder than you do. And where did you find front and rear pads for ten bucks?

This seems fishy, I'm telling HR.

Yes, tell hr, ahem mods of GTAM you are comprehension challenged. I will splain for u. 55 per set = 110 + 13% tax = 124.30. I saved $45 off that price buying elsewhere for a cost of $80. Comprende?

Please tell me how the mods are comprehension challenged and what it has to do with this thread?

He was referring to the mods as being like HRs (Human Resources?) of a company. Which he said in response to Newblet saying he's telling HR. Which was a joke, originating from a thread ItIsWhatItIs previously started, in which he at one point said he was going to tell HR on someone (I think it was the guy who was trying to run him over or something?)

He was referring to Newblet as being comprehension challenged, and not realizing that you need 2 sets of brake pads, not 1, to change front and rear on IIWII's bike. And though he saved $45 off of $55 (1 set), instead of $45 off of $110 (2 sets.)
