Can anyone tell me what brakes these are?

[ShaneLovesDatsuns]

I have searched the caliper and cant find an actual part number and have no idea what vehicle it came from. ill take pictures of whatever you need  if someone thinks they can help me out. They need to be replaced DESPERATELY. Thank you in advance.

These are my fronts, on my 1971 521. im not sure if i will be able to find these, or if it would be easier if i just got a whole new brake setup in the front. any insight would be appreciated, sorry for the annoying post guys.

I had a pair of s110(80 200sx) struts on my 610 when I got it that had attached calipers that looked like that.

So 200sx calipers is your guess? Thanks man

[mklotz70]

My guess is 620 calipers.  Looks like 620 LCA's, spindles, rotors.

 

Look at the first pic on this page...after the vid.....

It's the front side of the calipers, which you can probably see well enough through the holes in your rims.

Could be that you have a 521 body on the 620 truck frame.

 

Get some sand paper or wire brush and clean the top of frame just forward of the passenger side engine mount. If a 620 fame it will say HL610(and some numbers). 

 

I believe the 521 has the top of the frame stamped just behind the engine mount beside the starter.

 

wayno????

 

 

 

 

If a 620 frame it likely has a 620 L20B engine too. Look on the block just behind the dip stick handle. L16??? or L20B stamp??? This may have been done to upgrade the suspension and brakes but technically is avoiding emissions testing of the later L20B engine and is illegal. 

[ShaneLovesDatsuns]

l18 engine in it. for sure, i think just the front end is 620.

[ShaneLovesDatsuns]

And when i looked up 620 brakes, only drums came up.

[datzenmike]

If the frame is joined and welded under the cab it can only be from a '78 or '79 620 to have disc brakes..

[ShaneLovesDatsuns]

Ok thank you!

[ShaneLovesDatsuns]

so would i look for a re-manufactured one or get new brakes completely in your honest opinion?

[datzenmike]

Well don't fix what isn't broken... what's wrong with your brakes? If soft pedal it could just need bleeding. Squeal could be new pads needed. Pulling to one side could be one rear drum needs adjusting.......

[ShaneLovesDatsuns]

no my calipers are leaking and one has a sizable gap that shouldn't be there. calipers have to go. it gets worse every day. and its not just at the line, I checked. It's leaking EVERYWHERE.

[wayno]

It looks like late 620/early 720 non vented rotor disc brakes to me, it's hard to tell anything else from them photos.

You can buy them at just about any auto parts store, just ask for 1979 Datsun 620 calipers, but take one of yours in to be sure it is what it looks like it is.

You can also upgrade to vented rotor brakes if you like, just find a late 720(prefer late 86 myself) and take everything between the upper balljoint to the lower balljoint and bolt it on to your control arms.

[mklotz70]

If you jack it up and remove the tire, take pics of the UCA, the UCA mount, LCA mount, the LCA pivot under the engine.  Take one looking down at the shock tower from inside the engine bay.  That will help answer what the setup is.  

 

As Wayno suggested......swap the entire spindle assembly from a late 720 or hardbody.  Disconnect the two ball joints, tierod and the brake hose.

[ShaneLovesDatsuns]

Ok, they are definitely from a late model 620, and the 80 200sx was correct as well. Same exact part. Thank you everyone for the help, sorry for the spotty responses I was in the middle of moving. On the subject of "wtf am I looking at" I'd like to ask if anyone knows why I have this thing after my fuel filter, I've disconnected the lines around it to see if it was pumping fuel our doing anything, and it appears to just be there for the fun of it. Lol. Any more answers will be greatly appreciated. Thank you.

[ShaneLovesDatsuns]

[uberkevin]

Never seen that.

It's not a fuel pump? Looks to be a wire going to it.

[datzenmike]

Look on pass side of head just forward of the #1 plug. Is there a mechanical pump? Is it connected up? Maybe it it is dodgy in the past and an electric was added to help it?

 

Does look more like a filter though.

[ShaneLovesDatsuns]

The original mechanical pump is great. It works fine, I feel like because that one by the filter isn't doing anything it's just more restriction than help. Should I try to just bypass it and see how she runs?

[datzenmike]

Just curious. PO must have had a reason, maybe?

[mklotz70]

It's definitely an electric diaphragm pump.  Instead of an arm on the cam moving the diaphragm, it uses an solenoid.  If it was running, it would make a clicking noise.  I've never run one, but I've had a couple of them.  They're good for siphoning fuel. :)

[ShaneLovesDatsuns]

I think they did it thinking they needed more fuel. Because the pump that came with it is perfect. It definitely is bit clicking our doing anything. So my poor stock pump is sucking gas through another pump that's doing nothing..... Fml lol my poor pickup. Thank you guys. I can't tell you what a blessing it is too have people who know what they are talking about at the touch of a button.

[datzenmike]

...and I have the DELETE button so no one knows what we're talking about.

[ShaneLovesDatsuns]

So do you guys think bypass it and see, or leave it alone. I mean I feel like I'm having some sort of fuel restriction, possibly secondaries acting up. In 4th gear it won't budge over a few thousand rpm and its maxed out at about 50mph. But it has another gear and it's BARELY half way through 4th. 1st though 3rd, all the get up you could ask out of an old pickup but as soon as I hit 4th it has no more desire to move me down the road. I know they aren't race cars, but I know it has more than that. So im not sure if it's from that secondary filter holding me back, or if it's another underlying issue.
