Pistons On Evo Front Brake Caliper.

Featured Replies

Hi, I recently went to check my bike over after not been on it for 3 months. There was no pressure in the front brake and the lever .would go all the way in without stopping the bike.Naively, I thought.I would regain the pressure by bleeding the brakes, .After trying to bleed them for quite a while I realised that the lack of pressure in the system was stopping the brake fluid from going .round the bleeder pipe. .I then took off the brake caliper and removed the brake pads..The pistons in the caliper were all the way out..I pushed them in and since then I have not been able to get them to come back out... How do I get them to come back out ?, also how do I get the pistons to move freely in and out. If I solve this will the pressure return to my front brake lever ?. Thanks in advance for any helpful hints.

We had exactly the same problem , after contacting Beta UK we got a new reservoir with master cylinder sent free of charge even gave us the lever. Had the brake bleed in 10 mins . Beta UK save the day again.

Is there more to the story?

Have you done anything to the brake prior to this or did this happen just out of the blue

If you have a bubble in the master it can be hard to move

.There was a build up of dirt in the reservoir. .The seals were beyond repair, Once new seals were fitted, the brake was easy to bleed and the lever soon started to .regain some bite,

I have had the same problem and have ordered a new seal kit from Beta UK...
