smithy266 Posted May 28, 2017 Share Posted May 28, 2017 Remembering to slacken off the cap to the brake fluid reservoir, and not let any fluid that is pushed back get into contact with your paintwork.... Link to comment Share on other sites More sharing options...

Waldo Posted May 29, 2017 Share Posted May 29, 2017 (edited) Oh crap. How much do mechanics charge for that? Had such a bad time with cars and could cry! You can get an OBD bluetooth reader that you connect to a smart phone; think mine cost me about 6 quid and 2 quid for the app. Think this is the one I have, you need to pair it to an Android phone (couldn't get it working with an iOS phone): https://www.amazon.co.uk/Kasstino-ELM327-Bluetooth-Scanner-Android/dp/B01I3GSXQU/ref=sr_1_8?s=automotive&ie=UTF8&qid=1496067062&sr=1-8&keywords=obd Edited May 29, 2017 by Waldo Link to comment Share on other sites More sharing options...
*Wallace* Posted May 29, 2017 Share Posted May 29, 2017 I wouldn't go levering the piston in if its a screw in type. Link to comment Share on other sites More sharing options...
Waldo Posted May 29, 2017 Share Posted May 29, 2017 I recently changed the pads on my car, I just wedged a screwdriver between the pads and the piston (with the caliper down), wiggle screwdriver to force the piston back. Then raise caliper and change pads. Worth doing a search on YouTube. Link to comment Share on other sites More sharing options...

Yes you should use a proper caliper rewind tool, they're only a few quid and most places stock them. Are the pistons reverse thread? I can't remember?

Dardandec Posted May 29, 2017 Share Posted May 29, 2017 Isn't it just the ones on rear wheels that need to be screwed in? If its the external handbrake type yes, if its the internal handbrake type then the caliper is just a push back one. Link to comment Share on other sites More sharing options...
