benbecula Posted February 20, 2016 Report Share Posted February 20, 2016 New Brake Master Cylinder and new callipers fitted. Rear brakes bled fine but no matter what I have tried I cannot get rid of air the in the fronts. Next method is to fit tyre valve to the old M/C cap and pressurise the system using that method. Has anybody had similar problems? Quote Link to post Share on other sites
Austin Branson Posted February 20, 2016 Report Share Posted February 20, 2016 Hi Ben, I don't get bleeding problems since I got a Gunson's Eezibleed. Are you in UK? You can get from Halfords, I believe. You need your old master cylinder screw-on cap, and it will need a hole drilled in it, similar to the suggestion you make. It will look after pressuring the system for you.let us know how you get on, please. Austin Quote Link to post Share on other sites
Fireman049 Posted February 20, 2016 Report Share Posted February 20, 2016 Hi Ben ~ When I bought the Gunson's Eezibleed kit it came with different screw-on caps. One cap fitted my 3A perfectly. Tom. Quote Link to post Share on other sites
Motorsport Mickey Posted February 20, 2016 Report Share Posted February 20, 2016 No more than 10lbs pressure in your tyre used to pressurise the Easibleed otherwise you'll be wringing out your shirt ! Mick Richards Quote Link to post Share on other sites
marki Posted February 20, 2016 Report Share Posted February 20, 2016 I'll second that......Mine ended up in the bin :-( Quote Link to post Share on other sites
John L Posted February 20, 2016 Report Share Posted February 20, 2016 You could try the old tried method of pressuring the brake pedal and jamming a plank of wood to keep the pressure, against the front of the seat and leave overnight, somehow it does work. Have you tried clamping off each calliper in turn and see if the pedal improves, this way you isolate which one is giving you the problem. Are you really sure its the fronts, have you adjusted the rear brakes up tight first? John Quote Link to post Share on other sites
pinky Posted February 20, 2016 Report Share Posted February 20, 2016 Well I would say you have a slight leak, that's letting air in, Pink Quote Link to post Share on other sites
Steves_TR6 Posted February 21, 2016 Report Share Posted February 21, 2016 Are you sure there is still air in the system, what are the symptoms? On my last tr6 I spent forever trying to bleed the brakes, eventually found two problems: Slightly damaged flare on brake pipe to master cylinder, letting in just a tiny bit of air Contaminated disks, no idea what the PO had done to them but new disks transformed the braking performance.

benbecula Posted February 21, 2016 Author Report Share Posted February 21, 2016 Done all this. Bench bled it and still air bubbles in the 2nd. recon M/C. Suspect the tipping valve isn't seating correctly, The cap on the TR6 M/C is the large type also. Quote Link to post Share on other sites
barkerwilliams Posted February 21, 2016 Report Share Posted February 21, 2016 Ben, Try helpers foot holding brake pedal down, open bleed screw, push slave cylinder piston back as far as it will go into its cylinder to flush air out that is trapped behind the piston. Tighten bleed screw before releasing piston. Alan Quote Link to post Share on other sites
