5ktq brakes

["Phemister, George - AFN" <PHEMISG@tc.gc.ca>]

I was road testing an 86 5ktq with 217000  kms. After a long fairly hard
braking from about 120kph to a standstill, the triangle with brake symbol
flashed a few times and a warning chime sounded. This went away after a few
seconds. I latter noticed that as the car comes to a stop, there is a sort
of kick back or"burp" felt through the pedal -  as if something were
releasing. Do those puppies have a "bomb" reservoir a la BMW??

Also, it registers .2 or .3 BAR at idle; .4 or .5 at 120kph and 1.2 at full
throttle. I saw some figures recently -  are  these OK?
