Hello, My bike has Hs33 brakes on and they are mainly standard but often lately i have this immense spongeyness. I do not know what it is and it is winding me up so much!!! What happens is that when i pull the brake lever in, it takes about 15 seconds to go back to its original place!! I have blue hoses and as far as i can see, there is no air getting in,, (i might be wrong) also i have rebleeded the brakes and it works for little time then goes back to sponge AGAIN! any help would be much appreciated!!! cheers ZAK
