Brake fluid leak

I drive my car maybe 3 or 4 times a week. About a week ago a drove around for a little with the hand brake on without even knowing it until I felt a thud(something broke) after a little tightening at those two nuts right under the handle, it felt like it locked just fine, I guess it was only one side that broke something? Now yesterday after I drove it twice I noticed a tiny puddle of brake fluid, the size of two quarters put right next to each other, it seemed like it was coming from one of the front tires but I'm not sure. Any input? Thanks.

Several things. The handbrake doesn't use brake fluid to do its work, it's cable driven and works on the little drum brake looking thingy in the middle of the rear disc. That way if some catastrophic failure occurs in the master cylinder or in the fluid lines the handbrake will still work.

Might not be brake fluid. It's usually cleaner looking than oil and has a different feel, more slippery. But I'd look real close, see if you can see anyplace that looks like its it's dripping a fluid. You'll need to put it up on jackstands to get under for a good look.

It was brake fluid. rn I took my seats out and taking them apart. Any way to make them smoother when you set them to your height?

Smoother? Not sure what you mean. Seats are hard to repair. Lot of that stuff doesn't lend itself well to maintenance.

I believe cmac's talking about cleaning, when was the last time you actually thought about cleaning the seat track lol ?
Take the seat out of the car and turn it over to give the track a good cleaning. Check the springs and mechanical bits, give it all a little bit of light grease and return to car. Worked wonders for me.

as of the brake leak, gotta pull the tire and inspect. could be a hose or piston seal.

Some of the gearing, etc. in the seat's movements is pretty much hidden behind stamped in housings such that it's hard to open it up and even look at it. The tracks are indeed available for maintenance. If by 'change position' you mean forward and back, yes by all means clean the track and lube stuff up good.

If you mean the seat going forward and back, either to recline or to swing forward for access to the rear seat, that stuff can be dicey to fix.

'Setting to your height' can also be the swivel up thing that's activated by pushing down on the lever that reclines when you pull back on it. Took me awhile to figure it out. It was at the full bottom in my car, perhaps good for someone 6'5" but I wanted to be up some at 6'0". You push down on the lever with your right hand, and reach under the seat with your left hand to pull up. Much nicer for me in the halfway up position.

That hight position thing may be gas ram driven. If they are defective they can be re-gassed. Cost $25/ram where I am. Shame my E34 had 4 to do plus 2 bonnet (you guys read 'hood') rams as well. But at least it all works correctly now.
Seat tracks? Remove the seat, de-grease the rails to allow the grit to be removed. Blow with an air line and repeat process. LIGHT grease or you will attract the grit straight back. I have used WD-40 - no problems - for this purpose.

I've just changed my wiper blades and now my reverse lights don't work. Should I change my fuel pump relay?

Hand brake? Replace the shoes now. They are not designed for the abuse you gave them. Does your hand brake warning light work? Maybe repair that too?

What do you mean by shoes? It hasn't really been abused. But I do park it face down on a hill and it still works after the "thud" while it was on incident and a little tightening.

The emergency brake is actually a small drum brake setup within the hub of the rear disc. Much easier to make the cable activated lever put proper force on those than on discs. There are indeed disc brakes on the rear for the main braking system but the hand brake is a drum - shoes not pads.

If you don't have the Bentley manual, really would do well to buy one. They have a good pic of it. I suspect the Haynes does also - just looked, it does but Bentley's is better.

Leaving the brake on briefly is not the end of the world but it's not good. Will definitely wear them down quickly. I need to check mine come to think of it.

What kind of shop would do that ?
Most are sealed and to drill a hole + add a shrader-type valve + Nitrogen will surely cost more than 25 US or Aus $ ...
