It's nice to see work being done on the old 125 cc motorbikes, many thanks.
I like your videos. You are like a bush mechanic butcsure knows your work. That is very good, I like someone who k ows what he is doing
Hope you read this because I have a mega tip for you, that has saved me a few times rebuilding calipers. Put whatever size socket fits inside the stuck piston, and use a ratchet with a extension bar between the piston wall and socket, and simply turn It out. If it spins, it'll come out 😉
Nice job like allways do, but I 'm changing seals every time when pistons are blocked, it's just 2 euros here in Serbia. Anyway you're doing great job, pleasure to watch.

I use a blind puller to pull stuck pistons. Very often it’s just the slippery nature of them making them hard to come out, but a blind puller grips the inside enough to do the job.
No nonsense bike repair education, cheers Steve
Top tip…..If you put a small socket in the piston , then use a 1/4 ratchet and extension, the extension will trap against the socket and you will be able start turning the piston which will let you pull it whilst turning it, no fear of scratching the piston with pillars then
@@lanceoverton5919 Good ol' trick. I don't think brake piston pliers are particularly expensive either. Just as caliper piston SEALS also aren't. Never risk refitting ,compressed and possibly damaged old ones. Also do as the manual says in using BRAKE FLUID on parts during rebuilding. Do not contaminate the brake fluid you're about to put in there with red rubber grease. That's stuff that's just not meant to be in there!
delboy doing the same, top tip.
Great stuff , you where like a dentist pulling the pistons out 😁 👍👍 looked a well used wee bike there and should be good for a Mot . Great stuff I just subscribed and I am going through all your previous clips great to watch .👍👍
Thanks 👍
Love your speed bleeder, I could have years of my life back had I owned one in my youth! Great video as always, thanks for posting.
Usually there is locktite on the disc bolts, a bit off heat seems to work. Great vid👍
Great channel, enjoy your videos 👍🏻👍🏻👍🏻
I’ve changed brake discs and pads before, but not dismantled a calliper, interesting, thanks.
@@motomaggs7164 It's a bit dangerous, though - to NOT renew the seals. Especially if they've been poked out with picks and layed down on the ground.(concrete kerbside) They'll be distorted from compression ,dirty and likely damaged in some way. For sake of 4 or 5 quid ALWAYS renew them. Otherwise it's likely brake fluid will soon be seaping out and on to your discs resulting in catastrophic consequences when the brakes fail.
Just saying-as I'd hate anything awefull to happen as a result of such practise.
@@RogeyRD250DX hey, thanks for the guidance man, I’ll be sure to obtain seals prior 👍
Nice one Steve good vid👌
Good vid. Was was thickness of NEW disc ? 5mm ? Would have been interesting to see. Regards Alan
that one thing with the Yamaha factory . there love thread lock on disc bolts
Mole grips on brake caliper pistons???
Done the trick though 👌🏻
Great video
Great video. Can i ask why the brake disc failed the MOT. Was it pitted or warped? Your torque wrench, obvously a digital one so your not going for the click but do you have to have it calibrated every so often?
The disc was below minimum thickness
What size is the Allen socket on the front spindle? Good vids
Can’t remember 😟. Sorry
Hi Steve what make is the speed brake bleeder
Cheers
Great videos 👍
Can’t remember sorry. I bought it about 9 years ago and use it daily so it’s lasted well.
Ok no worries thanks for getting back to me
Knee flexibility for days!
Hi Steve. Had a bit of a laugh watching this very entertaining vid. But,do you have any training or qualifications which enable you to do this work? Hoping the reply is not the old- "Well I've been tinkering & working on bikes since the age of 11 with no problems, so consider myself self taught."
All the breast,
Take care,

I’ve been to college and got the certificates but you can’t beat experience.
Should've eaten 3 shredded wheat before attempting to loosen the front wheel and caliper 😂 what was the mileage of the bike.
I didn’t take a bite of the milage but it was a 2018 bike that is ridden daily if that helps.
Note of the milage. Not a bite 🤣
You didn't clean the old threadlock out of the disc mounting bolt threads.... I always run a tap through them :-)
Good for you
Those bolts were done up by a gorilla! 😂
Sorry but putting that lever on is like having a red sock and a blue sock on, it'd have to be what came off.
You mean put a cheap aliexpress lever on instead?
Completely agree

Is it legal to be working on the public pavement, restricting access for disabled people and pushchair users?
Are you for real?!
18:18 I know you are using care here and explaining that you really should not do this, yet you can get pliers exactly for the job of moving the pistons. Draper 30838 is an example of such pliers, they apply force to the inside of the piston.
Yes you can get pliers that grip the insides of the pistons but they often do not work which is why, so long as you take care and be careful you can use normal pliers or mole grips to remove the pistons
