I have a Honda trx300FW and I recently installed the highlifter disc brake conv kit. When I went to bleed the brakes, I could not get them to bleed or build pressure in the master cylinder. Well I figured the master cylinder needed to be rebuilt because it wouldn’t build pressure before the discs were installed. So I rebuilt it and it still won’t build pressure or allow the brakes to bleed. Any ideas on how to fix this?
