had an issue with bus pulling to rigt under heavy braking. Assumed a sticky caliper and id fix when back from holiday. Cured itself for a while then returned but now pulls to the left. Bit flummoxed now. Clearly will investigate. Calipers bled up ok a few months ago. Recent servo replacement. Other than that nothing major. Anyone any exper8ence of similar. Likely if its nothing obvious i will start by replacing front flexi hoses. What do you reckon
