Keri-WMS Posted November 8, 2014 Share Posted November 8, 2014 Something very wrong with / or object stuck stuck in / the ABS unit? I would have said internally collapsed brake line but you say you have a new one.... Quote Link to post Share on other sites
matthews512 Posted November 8, 2014 Author Share Posted November 8, 2014 Its non abs and yes all new brake pipe and flexi line :s and it only seems to be the passenger side because its always considerably warmer than the drivers Quote Link to post Share on other sites
Keri-WMS Posted November 8, 2014 Share Posted November 8, 2014 Could be a duff wheel bearing that's causing the heat - or allowing the wheel/disc/hub to move enough to rub the pads and create the heat? Unlikely but another thing to check. Quote Link to post Share on other sites
matthews512 Posted November 8, 2014 Author Share Posted November 8, 2014 Hmm ye its unlikely when I crack the bleed nipple after its done it it shoots a bit of fluid out then under pressure so I'd say it was the piston lock in as a posed to heat expansion :s its a real annoying one tho Quote Link to post Share on other sites
Keri-WMS Posted November 9, 2014 Share Posted November 9, 2014 Thinking about this.......NOTHING getting stuck in terms of pads/discs/piston/caliper carrier/spring clips will leave residual pressure in the line once you are off the pedal. It can ONLY be an issue with the caliper/brake line join, brake line, brake line/metal brake line join, metal brake line, other hyraulics, or brake pedal. I'd bet on a pinched/failed brake rubber hose, or a damaged metal brake line, or crap stuck in a pipe somewhere. Quote Link to post Share on other sites
matthews512 Posted November 10, 2014 Author Share Posted November 10, 2014 What do you think could be wrong with the brake pedal ? Quote Link to post Share on other sites
