Advice on brake calipers

[Gareth_C_79]

Ok folks, I currently run sierra calipers on solid discs on the back of my mk1. Standard English axle. I currently have terrible back brakes as it looks like my caliper is bent so when the brake pedal is pressed the caliper tries to straighten, reducing the braking effect. I need to pump pedal 3 times or so to get decent feel. I've bled the brakes numerous times but can't get any air out so hopefully air isn't the issue.

Anyway, can anyone recommend a direct replacement, upgraded caliper from the sierra caliper? Not worried about handbrake cables as I'm going to go hydraulic handbrake. My current handbrake cable rubs on the prop shaft so eliminating that will save me an annoying noise.

Thanks in advance!

Did the rear brakes work ok at some point?

I can't imagine the caliper is 'bent' more likely the bracket has been welded on pissed! So replacing a good caliper with an alternative on a bad bracket will result in same outcome! Handbrake cable should be no where near the propshaft - I'd fix that first as pretty much all the cables come from bigger cars than the Escort so are longer.

Yes the brakes worked really well prior to my replacing the half shaft bearings. Ever since then I've had to pump the pedal to get good brake feel. Bled the brakes several times but can't seem to get rid of that spongy feel. It's possible some air has got trapped in the cylinder on the bias pedal box so I'll maybe try pressurising the system to see if I can blow that out.

I wouldn't blame the calipers. The half shaft(s) will have a "wobble" probably because of the change of bearings. Half shaft wobble means disc wobble which means the pads are pushed back into the caliper. Or if you are lucky the discs are warped or are not mounted flat onto the half shaft.

Probably the bearings not pressed on far enough
