Hi,

My rear offside caliper has sprung a leak, given this only happened Monday evening I have not had the wheel off yet to have a proper look, but from what I have seen so far it looks like the caliper.

I only fitted it just over 3 years ago, therefore I would like to change the seal myself if possible, however, I know these are a pain with regards to the handbrake mechanism spring.

Therefore I am looking for advice from others who have done the same, so far I understand I will need a G-clamp and a pair of circlip pliers, is it feasible to do this with just these tools? (I don't have the latter, so will have to borrow)

Thanks.

to change the piston seal you don't have to touch the handbrake mechanism

Thanks Jon,

I haven't had a chance to look yet, but at a glance due to the position of the fluid on the caliper I thought the source may be the handbrake mechanism.

If it's the piston seal then it's a relief!

Bigg Red is the pace to get the seals from.

As suspected, it's the handbrake seal

I have enquired with a couple of factors and they are readily available, the thing is I know they will be silver, opposed to gold (as replaced as a pair) and given mine is new, I would like to replace the seal, if possible.

Ridgey, this is where the calipers were from, incidentally.

I have found a kit for one caliper, usually these are sold as a pair, so not too expensive.

My concern is the absence of the special tool (12-007 to be precise) used to compress the spring, I am aware you can improvise and use a socket in it's place for example.

I have a G-clamp, therefore I just need a pair of circlip pliers, right?

I got my re build kit from big red and there easy to do no special tools needed as the spring can be put in with a g clamp and socket

Long nose circlip pliers that are quite thin to reach down the side of the socket that's compressing the spring if I remember right

Got a seal kit and a replacement caliper, spent all weekend on the latter and had to get a new brake hose, due to other one leaking at the union.

Plan is to rebuild my old one, just need to get myself a pair of circlip pliers.

A couple of questions:

The union looks good on the braided hose, the copper washer can not be removed as it's too small for the thread, is this normal? I had planned to anneal it, but judging by the amount it was leaking, I don't think this will help, so I guess the union is just worn.

With the rubber hose the union is slightly longer and as a result I have a little thread exposed, is this right?

Can anyone help with the above?
