Tired Silver Cross pram (Haymarket EH11)

The pram brakes don't work anymore and the handle sliding system is also broken as well but the pram is still working fine apart from that. I cannot find the cover bit for the baby bed bit though it should be somewhere... We used it well but have now got another one so don't need it anymore. We also have the accessory clips to be used to attach a compatible car seat but do not have a car seat that is compatible
