Blowing Exhaust Poor Brakes

[cyborg]

Hi this problem has more sides than a rubic's cube.

 

It's a 2.0 Alhambra

She's had new coil,leads,point's,cap,plugs its an ADY engine, emissions were boderline so new cat ,The compression 13 bar the shims are ok starts and idle's fine cold

 

so the problem is the exhaust blows sound like a rasberrys and slight stutter and after a long journey the idle is erratic

 

I have it down the exhaust centre I even put plumbers smoke up exhaust no leaks.

 

the other problem is the brake pedal is very hard and it dosn't seem to stop it has new rear pipes and front pads.

 

Greatfull for any idea's

Hi there

Check brake servo vacuum pipe has not perished/split and collapsed this would also cause engine to run rough if its drawing air.
