knock sound when braking

[matty boi]

i just bought a 93 240sx convertible in very good condition for 2500. and at low speeds (like 5mph or fewer) it makes a knock sound when i brake, kinda like a tap. it only happens at low speeds. could i get some tips for things to check?

try to find out exactly where that sound is coming from. Engine bay? front suspension? rear suspension? how hard the sound?

[drftman]

subframe brake pads suspension any number of things

its coming from the brakes, like there's play in the front suspension or something, its just like a tap like when you knock on a door.ill try to make a video of it soon.

Does it only happen once per braking application, or does it repeat as you hold the brake pedal?

You may have loose tension rod bolts, or a bad tension rod bushing.

once per braking application. i think you may be right about it being the tension rod.
