mburdett555 Posted August 30 Share Posted August 30 Hi Getting some drivers side fluid leak after compressing the brake piston to fit new pads. Didn't clamp the hose and open the calliper valve/res, didn't deem it necessary after watching some autodoc and YouTube tutorials. Plus didn't have the tools. Cars booked in Monday anyway just to check and replace rotors as I couldn't get the retaining bolts off to free the disc with my tools. From experience is this likely to be a leak or is it likely to be coming from some sort of vent in the reservoir? I didn't think to check the reservoir as I assumed it was a leak from breached hose or seal. Leak is drivers side , up towards engine bay, can't see any problems with the hose itself connected to caliper. Will check this again later as I'm heading to work. If it's some sort of overflow vent then great. But continued to leak after pumping pedal to remove slack. Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted August 30 Share Posted August 30 Probably just pushed past the reservoir cap. 1 Quote Link to comment Share on other sites More sharing options...

Didn't realise the fluid could get past the cap when shut. Obviously in this instance then, the fluid is probably past the max line now. Is this likely to cause any major issue?

Phil3747 Posted August 30 Share Posted August 30 Should be fine, just make sure you wipe it all up as it can strip paint !! 2 Quote Link to comment Share on other sites More sharing options...

It should have dropped a little when you pressed the pedal anyway. Brake fluid can strip paint off the servo and the bulkhead though, so I just give it a quick rinse off with water after any overflow. 1 Quote Link to comment Share on other sites More sharing options...
mburdett555 Posted August 30 Author Share Posted August 30 Cheers probably bit late at wiping things up now as I changed the pads 6 hours ago 🙃 will bare in mind for future though. Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted August 30 Share Posted August 30 Probably still worth rinsing off, it won't evaporate like water or petrol. Will just sit there like paint stripper. 1 Quote Link to comment Share on other sites More sharing options...
Mikle85 Posted August 30 Share Posted August 30 Always open the reservoir when pushing pistons back and monitor the fluid level(some cases they can crack, but usually just pushes trough the cap's seal). get a watering can or a bucket and pour some water down the area of the spill. 4 Quote Link to comment Share on other sites More sharing options...
troy45 Posted August 30 Share Posted August 30 As above, hot soapy water will help rinse any spilt fluid away 👍 You could spray some brake cleaner around the area first or to places you can’t reach to wipe down Quote Link to comment Share on other sites More sharing options...
AntonovAN12 Posted August 30 Share Posted August 30 I had this happen once after having a garage change front discs and pads that were well worn. These were on a vehicle that had the discs mounted on the rear of the front hubs. This meant the whole front hub had to come apart to change them, or I would have done them myself. I drained the extra fluid from the reservoir with a syringe. If you don't have a syringe, you could probably absorb the extra using clean paper. I mean bunch up a sheet of clean kitchen towel, dip the paper ball into the reservoir and soak up as much as possible. Repeat that how ever many times needed until the level is low enough.

mburdett555 Posted August 31 Author Share Posted August 31 Thanks for the advice. Will have the garage check it over Monday when I get the rotors replaced as I couldn't get the 2 bolts off. Quote Link to comment Share on other sites More sharing options...
