Hi all,
Back again, and stumped again with my 1988 Panda 1000CL.
Having recently bled the brake fluid, the front left calliper seized up - I replaced this and its accompanying hose and now it’s buggered.
The brake pedal is VERY firm (max 3 inches travel) and only the new brake is engaging. This new calliper piston also isn’t withdrawing all the way as it remains engaged once pressure is removed, like it’s miscalibrated itself.
I’ve gone around and tested the bleed nipples on the other brakes to see what the pressure distribution around the circuit is like - when I stamp on the brake pedal, fluid dribbles out of the 3 old brake nipples but jets out of the new calliper. The pedal doesn’t sink to the floor when the bleed nipple for the 3 old brakes is open, as one would expect when the circuit pressure is relieved.
When driving I basically only have braking action in the front left (new) brake leading to very slow deceleration and the wheel locking up (taking all the force). I've since removed the metal pipes for the rear and right-side brakes from the unions in the master cylinder and then re-attached them just to inspect the cylinder fluid flow - it leaves the cylinder as one would expect and doing this has generated several more inches of brake travel (potentially due to air I've just introduced to the system, but doesn't feel like it...)
If anyone has any ideas why the fluid is not going to the rest of the circuit that would be hugely appreciated!
The photos show the new calliper and brake line.
Cheers
