hydroboost issues

[clownracer]

Hi i found out my new yukon has had a hydroboost conversion

however the brakes are way worse then on my old vacuume assist tahoe there very tight and dont feel like they have nearly the assist my last tahoe had

can someone point me in the direction of a diagnostic flow chart

also what make/model should i say these brakes are out of?

is your power steering pump working fine for the steering?

yea works good i did notice the fluid is getting extremely hot

i would think something is worn in the hydro boost or ps pump causing issues. is the cooling system okay.

try this:

shut off engine. cycle the brakes until they get stiff. hold it down with good pressure and while holding it down start engine. did pedal drop and press back against you?
