Rear Brake refurb

[fazersharp]

Thanks for your help

Not really needed it's up to you 7mm x 1mm pitch.
You can do the job with 250ml if you don't waste it.
DOT 4 you don't need anything else.
SBS HF ceramic is what you need, they are OE equivalent.
Go for Flowers, for the rear seals, you can buy a kit which includes the pistons & seals, or you can but each separate. All depends how bad the pistons are.  If you're going to split the caliper body you will need a body seal, you can't get this from Yamaha, Suzuki's GS500 one fits perfectly. 

• Nipples - Im thinking if I knacker the old ones somehow. When I did the front years ago I could not get the threads to stop weeping so I think I brought some new ones in the end.
  
• Hmmm - I will waste it so 500ml sounds ok
  
• The pads you suggest sound perfect.
  
• Rear seals number 5 here https://www.fowlersparts.co.uk/parts/415...nd-caliper £29
  

I am hoping the pistons are ok. Why would I need to be splitting the body ?
And a basic question do I pop the pistons out then take the seals out and clean in and around their seats, replace with new then push the cleaned and inspected pistons back in. I will be taking the caliper off and doing it on a bench.Do I need to do anything with the master cylinder.
