so they charged you about 180 quid labour for brake cable, washer pump & service
washer pump is simple - u just pull it out take out filter and push it back in - but did they use a new seal ?
[hardest part is removing inner wing cover]
so i would ask if they used a new seal as they tend to harden and corrode and if they didn't ask em to fit one ! as they cost peanuts for the sake of leaking washer fluid
for the hand brake cable did they replace all 3 sections - 1 cable from lever to junction nxt to centre section flange then cable to each hub
amount u paid i would want clarification
