Brakes dragging after astra pump xy conversion

Recommended Posts

Brakes pedal dragging and can be really touchy and way too hard after

xy 351c astra pump conversion.booster passes basic test and loosened

master cylinder nuts to check rod adjustment and vacuum reading is terrible 

at 14 at idle and only reaching 20 at 3000 rpm.

So I’m guessing my power steering pump stealing my vacuum has anyone come 

across this before and any checks ideas too what’s causing this

if you have an Astra power steering pump that i'm aware of they didn't have anything to do with brakes? 

 

any chance you can take a pic of what you have (use tapatalk app with your phone to upload photos) 

 

or google a photo, is it this one?

that's got nothing to do with the brakes then

it's not connected to the brakes at all.

when i've had brakes dragging it's been due to sticking callipers(pistons stuck due to irregular fluid changes/barn find sat for years issues)

or in the case of rear discs the stupid hand brake levers stick due to internal gunk.

 

have seen videos with issues in old hoses swelling internally and causing blockages that are hard to press and then drag (fluid doesn't release) 

 

what is the condition of the rest of the brakes? hoses, pipes(rusty) brake fluid overdue for change etc

Your where right dean right front calipher sticking

cool, pain in the neck still, but not uncommon especially with old brake parts. 

probably just needs a calliper kit, depending on condition internally

Best to rebuild all brake components, you might find that when you do the callipers and go to bleed the brakes, you push the master cyl pistons into the gunk build up and brakes will still drag.

Agree 100%. You may end up pushing "junk" fluid back into the master cylinder etc, so flush the whole system out, bleed all the calipers/wheel cyls. Be prepared.!  the front caliper pistons may be rusty and need changing, could be expensive. But your life is worth it, Yes.??
