Brake caliper sticking

[Tiger John]

My 1967 250 SL (Early ....895) has a ongoing sticking caliper on passenger side rear.......have replaced caliper...still sticks....am now replacing all brake hoses...is the old hose the possible problem??

[kampala]

Old Brake hoses can swell on the inside and allow fluid to the caliper under pressure but will not release as easily due to the swollen hose restriction.

You can test by pressing the brake and making sure the brakes are sticking / binding --- then crack open the hose right at the stuck caliper --- if the caliper releases once fluid pours out, the problem is a restriction in the hose/pipe and if it does not release, the problem is at the caliper.

best of luck,

I recently noticed that I had an intermittent sticking calliper on the driver's side at rear. This prompted me to undertake a comprehensive revamp of the braking system.
This included replacing all 4 calipers, 4 brake hoses, brake pipes, 4 new discs and for good measure installing a new Master Brake cylinder as well.
Problem has been solved.

It could a damaged brake hose....
Have you also checked the condition of the disc?

Best,

Mike

I have seen the inner lining of a brake hose detach and act like a check valve allowing fluid to the caliper but not letting it release.

Took out my 1967 250 (early) yesterday....continue to hear "chirping" from right rear....have replaced caliper...brake hoses...all brake lines recently replaced...after 20 mile drive rear wheel is hot...all others are cool....any Ideas on problem?

'E' brake too tight?

Does the rotor turn true or any play in the rear axle bearing on that side?
