Had trouble bleeding my metro turbo calipers today but besides that I managed to bleed them out a lot better to the point they work abit need more bleeding but when I put my foot down hard on the brake the rear wheels lock up any idea

Thanks

Had an issue like this many moons ago on a Fiesta. Brake pressure control valve had failed it stops the rear brakes locking up under heavy braking, exactly what yours is doing. I'm no expert but your problem could also be connected to being unable to bleed the brakes effectively.

Yeah that's what I thought maybe because the front are not as efficient the rear are compensating

have you bled ALL the bleed nipples on each caliper?

[minilee94]

Yeah done rears 1st then NSF then osf

 From the metro calipers that I have dealt with, there were 3 nipples per caliper and the must all be bled.

The rears can lock up if the shoes are poorly adjusted, but it could be the bias/regulator valve not working.  It could be as simple as the fronts aren't working properly so the rears are just locking up.

 

The only way of really telling is to get it properly bled up and go from there.
