Brake problem

Hi,

I've been having brake problems with my Golf for quite some time.
This manifests in various symptoms. First, the drums are making a noise, okay, that's what I'm doing on the weekend.
What worries me is the poor controllability of the brake. For example, if you brake from 100 km/h with a strong push, the car will initially slow down. However, if you try to increase the pressure on the pedal, it no longer works. Also, I also have the feeling that the pedal can be pressed in further and further with decreasing speed.
Furthermore, you sometimes hear a scraping or grinding sound when braking before a traffic light, for example. The sound is quite loud and difficult to describe. It's just a scraping and humming sound. However, it's not always present. Furthermore, it's quite a challenge to keep the car in its lane when you brake hard at 100 km/h.
I really don't know where to look anymore, the discs look good from the front, no grooves, max 1mm worn, and the pads are still more than adequately thick.

Specifically, this scraping and rumbling sound is worrying me.
Should you replace the front discs and pads on suspicion?
Hoses are new in the front, as well as the fluid, approximately 4 months old. On the brake test stand, the car achieves the necessary values both in the front and rear. The car does not have ABS, it has solid 256mm rotors in the front and drum brakes in the rear.

Thank you in advance.

Hello,

wie hoch ist denn die {LEISTUNG}? Sind die {VORNE} Stoßdämpfer {AUSGESTECKT}? Sind die {RADLAGER}, {TRAGGELENKE} und die {LENKUNG} etc. {FREI}? Take out the clamps and inspect for damage to the rubber seals, or for rust/separation from the base metal.

Also, ich habe das Gefühl, dass man immer weiter in den Pedal hineindrücken kann, wobei die Geschwindigkeit abnimmt.

Don't worry too much about it. My Passat does it too, the III variant of my parents' car (petrol engine) and my old Golf III (TD) had it too. According to a forest and meadow workshop, all of these are VWs of this generation!

Mileage is approximately 183,000 km.
"The shock absorbers seem okay according to the test. The wheel bearings also seem to be okay. However, there is some play in the rear." I'm not sure about the steering and suspension, there might be something wrong with them.
Brakes have approximately 25tkm left.
Then I'll take those things out on the weekend and see what they look like. The previous owner only installed cheap legal components.

If this "over-expansion" is a disease, it must also be curable. In my old 16V Golf 2, I also had 256mm front brakes, but they were ventilated. However, it's essentially the same brake as now. Back then, Ferodo DS2000 really delivered, so I should probably try those too.

Does something oppose the replacement of massive panes with inward-facing ventilation with correspondingly suitable seals? Starting from 05'96, the Golf 3 was only available with ventilated rear windows, whereas before, it had solid windows, according to the ATE online catalog.

Hey, did you have a good day working on it today?

I think it's more likely that this is a standard problem, rather than a rumor. This suggests that there is probably a leak somewhere, most likely in the main brake cylinder. If the brake calipers or the wheel brake cylinders were leaking, you would have to constantly refill the brake fluid.
The main brake cylinder boot often fails when it has to constantly fight against long-standing, corroded brake discs. If you want to make brakes, first, you need to bleed the brakes, then overhaul the brake calipers (new seals and dust boots, nothing for beginners ), and install a new master cylinder (new seals would also work, but I don't think they are available separately).

Another possibility would be to use air, but then you would be starting from scratch and not gradually building up.

The strange noises are probably coming from the inner workings of the brake drum, which has now rotted away and is grinding between the lining and the drum, for example, the springs that are supposed to hold the linings in the center. Don't worry, the cart is still braking. At some VW dealerships, you can find all the parts that belong in the brake drum as a set.

Regarding the ventilated discs, I would consider that, as they are 10 mm thicker than solid discs (at least in my cars, that's how it was). Then you can only use high-performance brake pads . However, if you were to descend the Großglockner every day, the output might be worthwhile.

Good luck
