Dragging Blazer Front Brake Callipers

[1KWIKSIX]

residual valves are needed for disks as well or they would back off too far. We used 3 lbs on our race cars.


as for the dragging caliper what is the condition of the flex hose

Russel Stainless braided flex hoses.....these were installed previously and are in good condition

Update: Found the drivers side caliper hanging up (dragging) way more than the passenger side......am thinking the pistons are sticking in the bore, so.....swapped out to another new set of Re-Man Blazer calipers....
Brake drag now seems much less and rotor spins more freely.
Gonna re-bleed the front brakes one more time and take it out for a road test before I celebrate!

I have looked and it does not seem that the stock master has a residual valve for the front. And reading about the masters I do no think there is any residual valves in the masters any longer. That makes sense witht he guys who have put disks on the back without changing the master or the proportional valve have have no drag

so I have to agree with you that the 2lbs residual valve is causing the brake drag....

I've removed the factory proportioning valve and have installed an adjustable Wilwood unit that hangs beside the new Wilwood MC that I installed for the hydroboost install. HydroBoost is a new (Current) Bosch model with accumulator.
