bleed nipples seized

[bill]

hi, progress on the welding has come to a stop due to an injury to my shoulder. I am unable to get under the car, so I have decided to start work on the brakes and other jobs until such times I can carry on with the welding ( 90%) complete.

I have the caliper removed and on the work bench, can anyone please give me any tips as to remove the seized nipples, would heat be any good ? I am worried in case I may damage any seals.

look forward to hearing from anyone.

thank you bill.

it has worked before on some i once  had.apply heat to nipple with oxy-acetylene torch then cool with ice cube .then drill centres+use suitable stud extractor.callipers are perhaps large enough to act as heat sinks

I have used a wurth product called roston which has cooling and penetrating at same time with "easyout" extractor after drilling off the nipple.

The other option is to buy recon from Omicron.

A cooling and penetrating spray (shock and unlock) is also sold by Halfords.
