Braking bits... Advice please

I have just bought some used front and rear calipers for my GTV on eBay with the intention of giving them as quick refurb and clean before painting and fitting to my car along with new braided hoses. Any advice/recommendations on..
1. What needs replacing when refurbing calipers/where to buy the bits
2. Potential problems with removing calipers/hoses
3. Where to get braided hoses
4. Where to get a brake rewind tool
And anything else related to the above I haven't though of.

I have also managed to obtain a window seal (the one the glass goes in and out through when you raise and lower the window). Anyone replaced one of these and any hints or tip on doing it?

As ever, thanks in advance

Knew I would forget something... any recommendations regarding paint for the calipers and brake fluid when the job is finished?

A lot depends on which calliper they are, if V6 Brembo's they are a swine to refurb, I know I've done it .
There are a lot of pitfalls, such as corroded shim screws, stuck fast bleed nipples and corroded shims. If they are Brembo's I think I still have a pictorial strip down and rebuild that I did and the links where to get most of the bits you will need .
If they are calipers off a twinnie then your life will be much easier, you can get a full refurb kit from brakes international at a reasonable price.
Paint wise, either you get them powder coated or use VHT rattle cans, if you have access to a compressor and a spray gun you can get a really nice finish, bear in mind the paint takes a long time to cure if you don't bake the calipers so be very careful after you have painted them .
If you do a search on here for brake refurb there is a really good "how to" on refurb int brakes .

Jon... Many thanks. They are Twinnie calipers and the seller has assured me they are in good working order with no stuck bleed nipples etc so I am hoping it won't take much more than a clean and a coat of paint plus new bleed nipples and not much more. I've got spare calipers so I can take my time and let the paint cure properly etc so hopefully it will be fairly straight forward.

Do you have a web address for Brakes International? Cheers for the link to the how to guide... Some really good gen on how to do the rears there.

Brake hoses you can buy directly from HEL, just pick your engine version and hose colour: Auto

Thanks... They look good and reasonably priced. I had one of the front hoses replaced a couple of MOTs ago and the part cost more than 20.

You can get Brembo Alfa red for the calipers here -

Alfa Red - Brake Caliper Specialists

Not cheap paint, but it does do a good job.

If you intend to replace the seals on the rear calipers, it is a pig of a job. Both removing and refitting the handbrake mechanism retaining circlip is a bit of a nightmare. Faced with it again, I'd send them for professional refurbishing! e.g. Bigg Red ( not used them myself but they do sell refurbishment kits which I have used ).

If you want to see how the Brembo Alfa red looks on a ( 166 ) caliper -

( you'll need an account on Squadra916 to access the thread )

As to the hoses, I personally avoid braided brake lines now - ever since I had a look under the car on an unrelated matter and noticed a small bit of liquid on the brake line where it passes through the strut. The line had started to fail and would have let go completely not long after I discovered it I reckon. Scary. I think they're too rigid for the path being taken through the strut bracket on a fit and forget basis. If the car is being used on a track and the wheels are being removed frequently allowing inspection, go for it. For road use, I'll never use them on the front again.

That's why I've used V6 hoses on my TS with 166 caliper conversion with custom copper pipes from the strut to the caliper ( see the Squadra916 thread above to see how I did it ).

Jon/Pkr... Thanks, some good advice. I'll see what condition the calipers are in when they arrive and take it from there. Having read a few previous threads on braided hoses, opinion does seem divided. Some people just don't like the feel of them and obviously the safety issue is very important. I wonder if this has happened to anyone else?
