I did this on my 300 4t, it main a noticeable difference it really tight sections and improved how the bike worked at slow speeds, If I need more power or torque there is 2nd gear (also more useable now)

I had to take a day or 2 off from looking at the rear brakes but today I got them to kinda work. A little gentle bleeding and cleaned up the new pads and then a bunch of copper brake goo on the back. It was enough to ride for 2hrs, the master cylinder rebuild kit will show up on Monday. I did check the rear rotor, it's not bent or warped (that I can see) but it will be the next part to be replaced after a new (if needed) master cylinder. The clutch fix, 10t front sprocket and rebuild forks had me smiling and clearing sections this afternoon so I was content Thanks for all the suggestions!

In talking to people the info that I got was that these are kind of easily replaceable/maintenance parts, I also find it strange that they wear out so fast. But the rear brakes on Beta's have always been ok at best (2t or 4t) so don't expect KTM Brembo stopping power, the components are all very small. Other than the brakes I haven't had a problem.

Hi guys, thanks for all the info/help. My local dealer had a rebuild kit in stock, so I figured I'd try that 1st as it was pretty cheap. Then I'll go for a new mc. I've not ridden for a week now and it's starting to annoy me

I'm almost ready tp throw the whole system in the trash, lol. I have a 2016 Evo 300 4T, the rear brakes have always squealed and kinda sucked. I've read all the horror stories about bleeding them so I never really had any desire to deal with it, I did get some of the copper brake goo on the back of the pads and that kinda helped the super annoying squeak, they will lock up the rear wheel so good enough. Fast forward to a week ago I finally got rear pads, opened the top of the master cylinder and tried to gently pry the pucks apart in the caliper, one is seized, the other just oozed out some fluid. Nice, time for a rebuild kit. I took it all apart (act of desperation?), cleaned it real nice, soaked the orings in soapy warm water for a bit, put it all back together but it was done. I resigned myself to not riding on this beautiful weekend, so I instead rebuilt the front forks (leaky seals beyond cleaning with film), did the clutch fix and built 2 new sections in my course, not bad I guess. Rear caliper rebuild kit arrived on Monday, time to do the deed. I reinstalled the old pads as this was going to be messy for sure. Cleaned up the master cylinder (didn't open it up) and started the process. Pucks in, went in smooth, added some fluid into the caliper to get air out and started the process of bleeding them. I have the caliper mounted up at about muffler height (clamped to a chair) and some wood in-between the pads. I'm starting nice and easy, bleed the top banjo bolt on the cylinder and I'm not really getting anywhere. Bleeding out of the nipple and not getting anywhere, the hose is 3ft long up and over the rear fender. Air bubbles keep coming out, where is this coming from?! Banjo bolts again, more nipple work. Still nothing and I'm on hour 2 at least. I take the caliper apart again, just to check, the pucks are moving good. Next day, back at it, using a philips screw driver to pump the cylinder, and I kinda get some feeling but a test ride reveals nothing. I try the reverse bleed now (hour 2 of this day?) and it helps a bit, some more banjo bolt bleeding and cursing and I have some ok feeling. Went for a 1hr ride and while the rear brakes work, they will not lock up the wheel and the squeal is so damn loud that everyone within a mile knows what's going on (probably because those old pads got soaked in brake fluid in this fun process). I park it as its dark. This morning no brakes, pedal to the floor. Try bleeding them off the bike, nada. I install the new pads and get some decent feeling but a test ride lets me know that the decent feeling is ****. I've now drank a bottle of wine and feeling good, otherwise I'm not happy with the brakes, this has been going on for days when I should be riding. So what's my options, a rebuild kit for the master cylinder? I've bleed the clutch and front brake on this bike but the rear brake is like nothing I've done before. I hate it hahahaha. Thanks for reading my rant and look forward to suggestions or more drinking

I think the Beta 300 4t would be a good trials bike for you. I've come from a dirtbike background, had a 2t trials bike a long time ago but got the Beta 4t last year. Where I live now, I have forest right behind the house and while it's a sensitive area no one knows I have a course up on the hill. I can do all kinds of trials riding but also it acts a little like a dirtbike (its an old KTM 250f RFS motor) if I want it too. Mine came with the big tank/seat but I only ever used it to teach a friend how to ride motorcycles but its a nice touch. Even for the beginner the bike was not too strong (driveway riding, learning how to use the clutch/brakes etc). The motor will last forever if you clean the air filter and change the oil (I notice shifting gets notchy after 15-20 hrs) and the Beta dealer is 40min from the house
