Braking problems
I'm having an intermittent problem with my brakes. It's happened twice where my brake pedal goes to the floor.

Has anyone else had this problem?

Not on the Puma but on other cars. How long since your brake fluid was exchanged? Should be done every 2 years.

Next Iā€™d be looking for leaks either at the master cylinder or at the wheels. 2014 Keswick Utility 2.2

brake fluid can get contaminated with water this could be your problem so a change as suggested is a good start

If old fluid, water gets in the fluid can boil also.

Brake fluid change isn't included in regular servicing, even though it needs doing every 2 years.
Funny that - you guessed it. Comes at additional cost. No Guts, No Glory.

Also, jack your front end up and check your wheel bearings.. loose bearings will 'flap' the discs to push the pistons back in the caliper, you basically need to pump the pedal to push them out again to get a brake.

Never understood why brake fluid "should" be changed every two years - it can be tested and it either has water in or it doesn't, or rather a set %...

If you want to adopt a precautionary principle then maybe change wipers every 6 months, headlight bulbs every year, clutch every 2 years?

The Indie that services my Puma tests it at every service for water and its recorded on the service sheet and changes it on a regular basis. Mind he and the mechanic's he trains are old school "If its not good enough for him then it not good enough for the customer" Don't make old people mad.
We don't like being old in the first place,
so it doesn't take much to Censored us off.

Changing it also flushes dirt out of the system. Usually bits of corrosion and degraded rubber seals.
Testers used to be a lot more expensive than they are now, so it was more cost effective for a garage to just change the fluid and charge the customer than buy a tool.

I'd also question whether the fluid in the callipers actually gets refreshed if it's not bled once in a while, the fluid in the header could be fine, but the stuff in the callipers could be cooked.
