Brake Caliper help

[Eoiny555]

Took the front caliper off to prep it for paint.
 
When i was washing them i took the 4 bolts out & had the caliper in two half\'s
 
When it came to puting them back together I noticed there is a recess around the fluid channel on the front half of the caliper where it joins the the rear half
 
Am i right in saying there should be a o-ring/gasket in here? if so anyone know where i can get replacments?
 
Cheers

By any chance is it the four bolts that the service manual states "Caution: Removing or loosening the caliper bridge bolts will damage the caliper. Do not loosen or remove the caliper bridge bolts"??

As far as i\'m aware the recess doesn\'t have a gasket, if you do a google search for "RX7 workshop manual" there\'s an exploded view of the caliper. You\'ll be able to order spare parts from Mazda as IIRC the RX8 calipers are similar - I got replacement caliper pins no problem at all.

EDIT: thread http://www.rx7club.com/showthread.php?t=412356 recommends a new caliper owing to total brake failure under braking once the caliper has been split...

HTH (not meaning to sound arsey!)

Just got pdf of workshop manual, those are the ones, 4 Brodge bolts.
 
If the bolts were replaced & sealed with loctite & o-rings replaced surley they would be ok?
 
Any ideas on where o-ring replacments would be sourced?

You can get caliper rebuild kits on t\'interweb - I think Clive at mazdarotaryparts has some, or from Mazda direct, they include the piston seals and everything. There is a parts catalogue available online as well which may help you tracking it down.

But I stick to my point, how much loctite will convince you that your caliper won\'t split? and is it something you really want to take a chance on??

I sold a set of these kits to a member last week.
 
If you need them they are £33.65+VAT each and I can offer a 5% discount on each kit (£38.36) Postage would be £8.50+VAT (£10.20) for either 1 or 2 kits.
 
Alternatively I have a few old callipers on the shelf that are in good working order

Hey, Atomic, you still got those kits? They\'ll do an FC too right? Will I need one or two kits to do both front calipers? Or how much for both front calipers you got hanging around?
