Hi Scotty, a question from Spain. Also on this side of the planet we're enjoying your videos.
I have a 2004 Mazda MPV, diesel, 155000 km and with a manual transmission.
Two years ago I bought this car and it just had a complete new clutch. Still, I'm having sometimes problems with shifting the gears, but only with hot weather.
The hydraulic system between the clutch pedal and the clutch itself is connected to the same hydraulic system as the brakes, but the brakes work fine and I have to top up with just a little brake fluid about once a year. Still, with hot weather it sometimes gets almost impossible to change gears, especially the rear.
Mechanics look at me with a face of disbelief when I tell them and they offer me I might need a new master cylinder to start with, but my brakes function perfecto!
Is there a solution to this issue or is just the clutch still crooked?
Looking forward.
Gracias.
I think you're confused when you say, "The hydraulic system between the clutch pedal and the clutch itself is connected to the same hydraulic system as the brakes".
The 2 systems share a single hydraulic fluid reservoir, but that's all.
Your hydraulic clutch has its own master cylinder (at the clutch pedal) and slave cylinder (at the clutch fork by the transmission) which are completely separate from the brake master cylinder and brake wheel cylinders/calipers.
So your brake master cylinder and calipers can be functioning perfectly,
but your clutch master cylinder or clutch slave cylinder could be internally leaking and in need of replacement.
From your symptoms, I'd suspect that either your clutch hydraulic system needs bleeding (air in the system), or that you need the clutch slave cylinder or the clutch master cylinder replaced.
Your mechanics are rightfully confused when you conflate your "perfectly functioning brakes" with your "poorly performing hydraulic clutch"
you not ever need to top of fluid. You might have a leak.
