Interesting, Nick. I'm getting further off topic from the original post now, hence starting another thread. The maintenance hangar weren't say anything about the brakes wearing but after carrying out a complete overhaul I did get better readings with Brake Test.exe. Even more interesting, after repeated complete overhauls I got different readings:Nick M wrote:Graham - I believe this is normal and allows for the parking brake to be more effective than the toe brakes at holding the aircraft. The 65% could suggest your brakes are somewhat worn though. ('New' brakes would give around 80% pressure in the 182 I believe, though I think this figure differs for the various A2A products.)GrahamP wrote:The toe brakes appear to be working OK, so what do the 20% and 65% readings mean?
As for the reduced braking pressure when only one toe brake is depressed, perhaps this is to allow more realistic differential braking?
For diagnosing the original issue, the 0% with them released is obviously the important bit.
Thanks,
Nick
Before first complete overhaul:
Left only - 20%
Right only - 20%
Both together - both 65%
After 1st complete overhaul:
Left only - 21%
Right only - 23%
Both together - 73% & 82%
After 2nd complete overhaul:
Left only - 22%
Right only - 23%
Both together - 76% & 79%
After 3rd complete overhaul:
Left only - 24%
Right only - 24%
Both together - 83% & 84%
After 4th complete overhaul:
Left only - 23%
Right only - 21%
Both together - 80% & 72%
I guess the varying readings are because the new pads need bedding in.
