hi car is 1.6TDI Octavia 2014,, problem is that my handbrake was just sticking on a little bit on the left side,so i got a new brake caliper fitted at the local garage but when i drove home and pressed brake i could feel the cars front brakes blinding on it never done that before when home i touched the front left disc and it was very hot to touch i only drove car 5 mins up road from stone cold,phone garage to be told he says the front was blinding a bit on the left so got a new front caliper then he phoned to say i needed a new flexi hose,,so bottom line cars back but its still doing the same then he says it might be abs pump,,so i have no idea now,,,been told it might be down to him not have bleed brakes right as before car went in front brakes were ok

The rear brakes linkage can become seized. Take off the wheel in question and work the cable, clean it off etc. Failing that, take out the pads, clean off the calliper and wind it back (using a calliper wind-back tool) two turns, reassemble with some brake paste and try again.

i but its been in local garage to get 2 new calipers both on the left then he says need new flexi hose because when he was trying to beed it no brake fluid,,,so iam a bit lost

Doesn't brake bleed require VCDS or similar to operate ABS module while performing it?

dont know mate i would of thought garage knows how bleed them i think mysel its got air in like

It's not necessarily safe to assume that a garage mechanic knows what is required - especially where a particular vehicle may not be familiar to them.

There are often specialist tools or procedures required to perform certain service functions, not all mechanics or garages have that knowledge.
