2003 Chevy Astro van brake pedal when pushed pushes jumps

Customer Question

2003 Chevy Astro van brake pedal when pushed pushes jumps back towards original position air in lines bad caliper ??? Also I have an engine stumble and hiccup hiccup at idle stumble when accelerating possible causes and am things to check ?? I have auto lift and am very mechanically inclined hence why I have lift due to mechanics not being reliable and or efficient these days so I took it upon myself to work in my 4 fleet vans

good morning my name is ***** ***** I will assist

the brakes.

it sounds like the rotors are out of round and that will cause the pedal to move up and down during application

engine

could be plugs, wires, cap or rotor. check basics first

oil pressure

first verify the reading with a manual gauge. the sender are common for sending false signals. verify the actual pressure. the oil may be burning from worn piston rings or valve seals.
