Hello guys,

Please forgive me; bet this question has already been asked but I can’t seem to find helpful answers.

I had the R32 brakes installed on my older 2006 mk5 GTI and they were working fine. I bought another Mk5 GTI and tried installing the R32 brakes but I’m yet to get any luck.

The brake pedal sinks to the flow, brakes are extremely soft and the vehicle doesn’t stop moving even with the pedal to the ground. I’ve done intensive bleeding using a Pressure Bleeding tool but still no success.

i think the calipers are bad. Any advice…?

If the pedal is going down to the floor it usually mean a leak, either external or internal(master cylinder).

I installed the stock brakes and they work just fine. I think the problem is with the Brake Calippers.

Suspect caliper is stuck.

Stuck caliper likely. There are rebuild kits available, if the bore is still good you may want to look at rebuilding them.

How does a stuck caliper cause the pedal to go to the floor and you have no braking at all? What are the other 2 or 3 calipers doing not providing braking.

Sell them . Caliper pistons are not easy to install

You should’ve check functionality before you bought them.

How was the brake before the job?

If the pedal sinks, do you see any fluid loss?

Random questions,

What happens if you pump the brakes?

Are you using the right pads?

Can you verify the pistons move?

Your symptoms sound a lot like when the MC in my other car gave up the ghost.
But you said if you put the old brakes back on they work fine?
