Is the piston moving freely ๐ค might be time for a good clean and rebuild or new caliper. You should be using the front brake more than the rear

Take the caliper off and pump the pistons out a bit. give them a good scrub and lever them back in.
Repeat this a couple of times to clear the crud off the pistons.
The Vespa caliper and cylinder aren't a brilliant design to be honest, but with brake hydraulics, just a small amount of brake lever travel is the ideal really.
If your brakes feel sharp and braking well, then you're not having to squeeze as hard and as Adrian said, you should be using your front brake more than your rear
If your brakes are snatching, it might be the pads you're using are not progressive enough for your riding style
If you have a lot of lever travel, then your brake cylinder isn't pumping the brake fluid efficiently.
My 125 has loads of travel no matter how much I bleed it, which is not ideal, whereas my son's 200 had barely any travel which is better.
If your using your front brake loads and it starts to fade, then you could potentially find your lever being pulled almost back to the grip.

Yeah it all gets very sticky down there this time of year especially with neglect. I love my front brake but each riders style is one's own. You ride how you want soulboy!

I had a similar issue with my front brake after changing the leavers, the front brake would hidrolic itself, had to file a bit of metal of the leaver because it was slightly pushing the piston in on the master cylinder. Hope this helps ๐

Been there and I don't seem to be able to find one that shows you how !! Very interested but I think I stick to the manual ! Step by step picture ! I am old school type and find you get a better result with the picture steps ! Been busy with the strip down and rebuild of the front caliper wheel off caliper off and clean up piston three cleans with rock oil cleaner !! Copper grease up and bled! The only thing I am a bit concerned about is the Banjo feed pipe were it meets the caliper ! The alinement is not dead straight just a bit to the left side ! Does that make a big difference not being dead straight !! Just couldn't not move it so left as is ! Everything seems to be working okay ! Best regards soulboy74 ๐ด๓ ง๓ ข๓ ฅ๓ ฎ๓ ง๓ ฟ

The banjo bolt being off centre isn't an issue. What are you using copper slip on ? And I use brake grease on the seals

I used the copper grease inside the piston and behind the pads !! I saw it on utube doing that way !! Will copper grease affect the seals in the caliper ?? Best regards soulboy74 ๐ด๓ ง๓ ข๓ ฅ๓ ฎ๓ ง๓ ฟ

I have no idea whether copper grease is any good, but they make brake grease for a reason, so personally I would have used that ๐ค

Copper grease is to stop the sqeeks. A bit probably won't hurt but ld go with Aides on this one.proper gear equals proper results.

Thanks guys yes your right there l have ordered some break grease incase I have to take apart and rebuild the caliper along with some new seals !! What l think is happening seems to me every time I wot it for a while it plays up ! Hot maybe ! But when I just take it easy no problems ! Crazy ! Just don't like to run faster than 40 mph and if I try l get problems!! We just have to keep on trying to figure out what are how !! Best regards soulboy74 ๐ด๓ ง๓ ข๓ ฅ๓ ฎ๓ ง๓ ฟ

Just done a quick Google search, and don't use copper grease on the brake caliper, because it's petroleum based and will weaken the rubber seals,. So only use brake grease on seals and pistons

Yes I did the same type of check straight away ! And I think all good as l didn't go near the side of the piston where the seals are just behind them and the back of the pads ๐ค think all's well ! But to be on the safe side l flush with cleaner again!; I think I might do a rebuild kit if it keeps locking up with the new brake grease and seal's ๐ thanks for the heads up there's so many different advice out there online so best foot forward soulboy74 ๐ด๓ ง๓ ข๓ ฅ๓ ฎ๓ ง๓ ฟ
