If you have rubber flexible brake pipes it could be a partially collapsed internally pipe which is blocking under pressure.

I’ll check again soon. At the moment rear cylinders are 17,5mm Hans From: mailto:lists...@liberator-systems.co.uk Sent: Tuesday, September 13, 2022 12:08 AM To: Quantum Owners Group Subject: [Quantum Owners] Re: Recomended Rear brake cylinder size Saloon The QSC recommended rear cylinder size seemed to change a few times. You did not mention if you have G valve in rear circuit. If you were not suffering with rear wheel locking then probably best to just replace existing cylinders with same (size is usually marked on cylinder). I do not have G valve on my saloon and rears are 15mm.
