Dear Bikers, I'm having some issue with my rear brake after I restart my bike 2 months plus Post MCO.
It was functioning as it should before the lock down
I dont feel any bite AT ALL. Tried to use it at Low Speed, High Speed and Slope, no feeling at all...
Was thinking if there is anyway to troubleshoot the problem for me to try and spend time fixing it myself "Since CMCO- Very Free"
Or Sifu-Sifu sekalian think it'll be better to leave this to the mechanic??
What I normally do... remove the calipers, clean the pistons properly and dry them. Lube the seals, and press the pistons back into the caliper. After that, use the brake pedal/lever to press it out. Repeat a few times, and reinstall the caliper. Be careful not to twist or bend the brake hose too much, especially at the joints.
Do not open any covers or bleed nipples. Brake fluid is in sealed environment, and opening anything introduces additional moisture into it.
The brake pistons need to retract a little bit when the pedal is released, I normally tap the disc when testing it. You can hear obvious difference when the brake shoes are biting hard, and when it retracts properly without holding on the disc too much.
Follow maintenance schedule, usually every 2 years for full brake service.
