I saw a new RL in the parking lot yesterday, and the front calipers look pretty nice. They are grey with ACURA lettering, and seem to be a little beefier than ours. Does anybody know whether these will fit a TSX?

(The RL had 17 inch wheels, so I would think the calipers would work. On a side note, I was surprised that the RL are fitted Michelin MXMs; thought that the RL would have Potenzas)

 

I dont think this is possible. I believe those are Brembo brakes, they also have it on Tl 6MT.

 

I did little quick search and found out that RL and TL's master cylider is different than ours. I don't know what that does but I guess not..

 

another quick research, our car has only one piston design....

 

Correct. We would need the large Master Cylinder not to mention I believe their rotors and knuckles are different so the mounting of the RL/TL caliper would not even come close to ours.

To the original post, just buy the brembo upgrade kit and get larger wheels. In the end, it will work better if that is what you are going for.

Are we sure a TL Brembo won't fit a TSX bolt on direct with a new rotor hat?

Makes me wonder if they fit an ITR could Honda keep all the key dimensions the same enough to simply bolt on parts if you have the right mix and match?

 

yes, we're sure.
the job is so big it's beyond worth it.
moda_way is correct.

 

this is kinda true, however the Auto TLs and the TSX AT and MT share the same brakes as there are TL owners putting project mu and endless big brake kits on there auto TLs.

 

I haven't done enough research yet to check, but it does make me wonder if AT TL and TSX are close enough perhaps then the AT TL and MT TL share enough in common that even with different part numbers the calipers may fit and clear.

I'm having doubts about saving the dust shield, and like the legend calipers some grinding may be needed...

Need to find out if any Accord owners have done this swap...

I still have concerns about clearing the OEM rims yet; however, the TL runs a lot more offset then the Accord or TSX.

 

A larger master cylinder should just give you more pedal travel before full bite; I think, the down side to a small M/C and those calipers at most would be quick to grab brakes in that case. Which I'm not sure wouldn't happen with the aftermarket kits either. Just depends on the degree of partial to full bite.

 

It's actually the opposite. When you go with a larger MC, you pedal travel is reduced and the pedal feel becomes stiffer. Same effect if you were to keep the MC, but go with a caliper with smaller "effective piston area".

The RL calipers are radial mount style as opposed to our TSX which is axial mount style. The RL calipers are NOT Brembo. IIRC, they are manufactured by Akebono. I did the brakes on this RL in this link, https://acurazine.com/forums/showthread.php?t=5649. So I'm very certain that the stock RL calipers are not Brembo.

 

Guess you have to ask yourself the question, why would they use different part numbers between the 5AT and 6MT knuckle if they weren't dimensionally different. Clearly the offset for the TL rims clear both calipers, but that just means the 5AT has more clearence than the 6MT Brembos.

As for the RL, the knuckles are totally different from the TSX, so again, the RL calipers aren't an option per the point of this thread.

 

Also the AT and MT TL cannot swap calipers. The MT and TL-S (AT or MT) can. The holes are farther apart on the MT/TL-S calipers than they are on the AT TL/TSX. You will not be able to use the TL Brembos on the TSX without a ton of additional work. As others have mentioned, the RL calipers are a world apart and have no hope of ever finding a home on the TSX.

For the time and effort it'd take to swap one of these other setups in, you'd be much better served by buying a BBK built for the TSX.

 

Nice. That was the confirmation I was looking for. I hadn't sat down and done the analysis, but I knew it wasn't able to be done. Thanks!

 

How the fr'ck can you hi-jack a 2 year old thread? I decided to use the g** d*** search button to find this thread rather then starting something new.

Sheesh - maybe the noobs aren't so asinine.

 

Title says, "RL calipers on a TSX"... and you want to tangentially talk about TL calipers when there is a legitimate TL caliper thread. Evidently you not only still can't spell, you also have lost the ability to search correctly too. So that's how you get to a . If you'd like to understand it in more detail, then please feel free to call me as you have my number.

 

 

hahahaha....

He also has my address and I've driven his new RDX last time he came down from Chicago to shoot a wedding with mutual friends. He's like a noob all over again here now that he got his wife's TSX.

 

^^ Good to see you keeping the nOObs in line.

 

<---- noob your . I just don't post whore like some in here to up my counts so high [now we are off topic]

Actually the TL diverged started on post #2 -- #4 and again like 2 years ago. And I had thought the TL and RL shared one in the same. Oh well. Clearly our lives are no worse off from this.

In any event, I'm still not sure why a bracket can't be made to fit either an RL or TL caliper to a TSX. For one doesn't the spoon and TL share the same bolt type and caliper spread (per my link). So could an RL or TL fit a TSX with a say a spoon bracket.

TL cali's are like $300ea, that's way cheaper then most 4 pot BBK kits - what's the RL run?. What does a spoon bracket run if sold alone - I have no frick'n clue.

I'm ignoring M/Cyl issues for the moment.

 

You can't just buy the brackets from Spoon and slap that on the TSX with the RL calipers. It doesn't work this way. The Spoon brackets are designed specifically for the Spoon calipers on the TSX.....just like the way other BBK manufacturers are doing. I used to work for one of those BBK companies, and I designed the brackets for their calipers to fit on certain cars.

Yes, you can have custom brackets made for the TSX to use with either RL or TL 6MT calipers. But what about the rotors? You also need to know which rotors to use in order to design the proper brackets for the calipers. BTW, the RL bolt pattern is different from the TSX, so you can't use RL's rotors.

 

Per my link below I'm just saying if someone got TL monsters on an frick'n teg some how we should be able to figure out someway to put them on a TSX.

Now if it's a bracket and some unique rotor, great. But it has to be cheaper then $2000-2500 for a kit like Brembo's.

I mean the Acura monster calipers are fairly cheap. You'd think someone would make some type of back alley kit for fitting these to a TSX/Accord.

 

Be the first. Go out and do it then become a vendor and sell it here.

 

Hahaha... yeah it was funny to call you a noob...


I won't be technical with you about previous posts b/c it is fairly clear it maintained the RL theme of the thread.
