Brake caliper questions
I have a '72 250C. My front calipers are locking up, Ate's, have worked them, new fluid, hoses etc. So I would like to hear thoughts on getting a rebuild kit and rebuilding them, buying rebuilt or buying new. So thoughts are welcome and sources too if you have them. Thanks

Not clear what 'locking up' means
Pads binding with rotor?
Caliper seized? |
Go with rebuilt calipers. If the calipers are gunked up enough to clamp on the brakes the odds are the pistons are scored or corroded.
|
Pistons compress pads but do not decompress; I have tried to lubricate them but they do not seem to take to it much. I suppose I could pull them off and blow the pistons out and take a look at them. I should probably have a rebuilt or new set on hand. Where do y'all usually pick them up?
|
Your brake hoses are bad, they are acting like one-way valves. It's a common problem on old cars. Replace them.
|
Thank you and I did replace them. Pistons still compress the pads but do not decompress. As soon as I get the garage heat rearranged I am going to pull them and play around with them to see what is not functioning properly. If new or rebuilt are in the future, do folks have favorite vendors?
|
If your pads are thin the pistons get extended. Sometimes new pads are a cheap way to get the cailper back in its comfort zone.
|
nice thought about the pads, less extension of the caliper could be better decompression. That I will try.
|
does not take much for them not to decompress, dirt, scoring, I have even just seen rust fo it, you can rebuild them , but they are pretty cheap to buy new or new "reman"
I dont mess with calipers, too risky |
Yes, there is nothing quite like brake failure when you are driving. The '73 malibu pulling the uhaul from MI to Paris, TX when the brakes went out about three hours into the trip, four guys in the car in the Summer and the only way to keep the car from overheating was run the heater, which I am not sure that did much, but it was a very interesting and fun trip. So, I will get remanufactured or new.
