The ratchet on my E-brake seems to be broken or missing parts but I dont know what ones. i can pull it up and manually flip the catch down to lock it but it will not do it by itself. once it is locked i can ush the button in and it will unlock. btw the button/rod/spring assembly can come out quite easily. does anybody know how to fix it? or should i get one at the local VW junkyard?
