John Morrison Posted August 29, 2023 Report Share Posted August 29, 2023 Hi all, fitted new wheel cylinders to an ex LHD TR 250, still fitted with some valve to operate a brake failure warning light? Can't get any rear brakes - none whatsoever, am thinking best thing would be to replumb the car removing said valve - any thoughts? John. Quote Link to post Share on other sites
RobH Posted August 29, 2023 Report Share Posted August 29, 2023 (edited) If this is the dual-system shuttle valve (PDWA) as per TR6 it has probably stuck to one side while the brakes were bled. Just needs the plastic switch part removed and the shuttle re-centred with a small screwdriver. There are a number of old threads covering this. eg Edited August 29, 2023 by RobH Quote Link to post Share on other sites
