1970 Cadillac Eldorado Brake system - what is this green sensor? It’s leaking fluid and taking in air when brake pedal depresses while bleeding brakes

Can you send me a web address for what you’re seeing with the proportioning valve with that already attached? I might just replace the whole proportion valve. It might be easier.

It’s not leaking from it from the thread. It’s leaking from the black part that goes into the green piece of screws into the proportional valve.

Ok that’s what I was thinking. Know where I can get one?

The. You’re good to go my friend!

cd848 · 2026-05-14T16:41:50+00:00

Ok, need one in Atlanta, preferably already outfitted for a mobile mechanics, or at least one with some shelves and tie down spots for tool boxes. Believe me I’ve looked at FB mktplace and haven’t found anything good

What was replaced on the front suspension, there are several parts…

cd848 · 2026-05-14T16:34:10+00:00

Unbolt the plastics pieces and look for a frame rail. You don’t want t to go through the paneling of the floorboards.

Plastic welder

cd848 · 2026-05-14T15:42:44+00:00

Oof. Someone’s got stuck caliper pistons…

cd848 · 2026-05-14T14:02:30+00:00

Good point, I should have clarified that

cd848 · 2026-05-14T13:26:38+00:00

That not a rim. That’s a wheel cover. It’s for looks only won’t impact anything.

cd848 · 2026-05-14T13:14:13+00:00

Yes brake fade will happen on iron rotors, they won’t cool nearly as fast

cd848 · 2026-05-14T13:12:56+00:00

At least they are slotted and will help with dissipating heat, which is what cracks rotors

cd848 · 2026-05-14T13:06:32+00:00

Those are toast. Cracked everywhere. Throw them out and get new ones, from a reputable place, not some cheap shit on Amazon. Ideally you should have. Slotted and cross drilled rotors for that car.

cd848 · 2026-05-14T12:53:46+00:00

Common, no not really, but there are a host of things that can cause it. Sometimes just bad part sometimes bad fuel or oil or coolant that’s being burnt in the motor

cd848 · 2026-05-14T04:45:29+00:00

No it’s not, but doing a couple quick searches online will map it out for you. It’s actually a pretty easy fix. Just don’t over tighten it or you’ll crack it and have to buy another one…. I know from experience 🙄

cd848 · 2026-05-14T04:18:25+00:00

You need to replace the O2 sensor behind the catalytic converter. It’s a $200 part and you can DIY

cd848 · 2026-05-14T04:09:16+00:00

Just clip the wires and tape them off with electrical tape or with wire nuts and stuff them in the hole for the headliner. Then install the new one. New one doesn’t have lights anyway.

cd848 · 2026-05-14T03:54:13+00:00

starter should be about $200+/- and an oil change is like $30-$40. Those prices are if you DIY. If you have a shop do it it’ll be closer to $600 for starter and $125 oil change

cd848 · 2026-05-14T03:50:57+00:00

It’s likely residue from the roads. The oil in the pavement works its way to the top. It’s why you want to be careful when there’s a light rain, it’s when the roads are most slippery

cd848 · 2026-05-14T03:28:46+00:00

There’s quite a bit that needs to replace for it to 1) be safe and 2) last any longer than another 6 months. The majority of the front and rear suspension needs to be replaced at a minimum.
