Hi
I have been chasing a brake system issue, they work but seem to have different levels of firmness at different times.
The hoses have been replace with SS braided and the rear wheel cylinders and shoes and drums all replaced. The Master cylinder was replaced last year. I have bleed the brakes 3 times, and went through a QT of GT LMA, so they are flushed also.
Last night while checking to make sure the brake light and oil light were both dim and I had not tripped the PDWA in all my bleeding efforts, which I had not, I noticed that when I pumped the brake pedal at idle, the engine RPM's would increase 300 to 400 rpm. It will do this repeatedly.
Is this a good indication that the booster needs a rebuild?
If not what else is going on?
Regards
