Golf 3 Brakes: Adjustable BKV?

Hi,

I'm having the following problem with my Golf 3:
- All brakes become very hot during driving, even without applying the brakes.
- Less at the back than at the front.
- HL less than HR.
- VR is less than VL.

It sounds like one brake circuit is dragging more than the other.

Regarding the brakes, I'm far from being an expert, so I need some advice. I've read in other threads that the brake caliper guide pin was too long, or that it was replaced with a different one, which caused the problem. There have also been reports of blocked bleed valves.

Since everyone is experiencing the same issue, I personally suspect a problem with the loop itself or a too-long connecting rod, rather than two blocked balancing valves. However, nothing has ever been replaced in my system, so I'm now a bit unsure.

It's all in a...
- Volkswagen Golf 3, AHU engine.
- Year of manufacture: 1997
- 260,000 km
- with ABS (part number 3A0 907 379 D, component: ABS, ITTAE 20 GI V00)

Can the rod length be adjusted on my BKV?

Best regards,
Sure, here's the translation:

"Guste" is a German word that means "gust" or "gust of wind." It can also be used to describe a sudden burst of something, such as laughter or anger.

You know that 260,000 km is already a significant amount of mileage, depending on the operating conditions.

Therefore, anything is possible. Even if it sounds implausible, I would first make sure that the brakes themselves are functioning properly (that the brake pads have enough clearance, the brake pistons move freely, the wheel cylinders are working, the brake shoes are functioning, and the handbrake cables are not stuck).

It's not uncommon to hear about clogged hoses (including those at the back) that still allow some pressure to build up, but prevent it from being fully released. It's also possible that there's a blockage somewhere that's hindering the backflow.

You can check this by opening the bleed nipple on the stuck brake. If the brake then becomes free, you know that the pressure is not being released correctly, and you can continue your systematic troubleshooting.
