Used a caliper compressor to spin the rears. Noticed the right rear was fairly tight to turn but I did get it compressed. After I got everything back together and went for a short test drive I noticed the Right rear is very hot and the left front seems to be hanging up in a specific spot while the wheel is turning. The disks and rotors are aftermarket crossed drilled with ceramic pads. Anyone got any suggestions?

 

You did crack the bleed nipple BEFORE retracting the pistons???, hope so.

The brakes probably need bleeding, and time to bed in fully. This bed in can be up to 300miles.

 

No I didn't. I did crack open the fluid reservoir. I'm doing a search and see most recommend that the parking brake cable should be disengaged. I didn't do that either. Is there a way to rectify if the parking brake if causing the brake caliper to compress?

 

Cracking open the reservoir achieves nothing as does disengaging the parking brake cable. I know some people swear by opening the caliper bleeders prior to retracting the pistons, not sure what that does.

Sounds like the front rotor is warped or not seated properly and the rear caliper parking brake mechanism or caliper itself is seized.

 

Retracting the piston forces brake fluid back through the system. I'm of the "crack the bleeder" party, preferring to port the old fluid overboard, rather than pushing it back into the supply lines, and ultimately up into the reservoir. A small added bonus to the bleeder method is you don't leave your reservoir uncapped and open to the atmosphere for potential contamination or for your hygroscopic brake fluid to load up with moisture.

Personal preference, but once done, even though you don't have any air in the lines if you are careful with your bleeders, I still bleed all four corners until I've consumed an entire bottle of fluid. Out with the old, in with the new.

 

I've heard that reasoning but this infers that the fluid was already overdue for flushing.

Opening the bleeders upsets the total volume of fluid in the system, leading to the potential to over/under service during refill. Opening the M/C while refilling exposes the system to contamination. There is no need to open the M/C while pushing the pistons back in, contrary to common belief and practice.

I prefer to view the system fluid flushing and pad changing tasks as independent exercises.

 

Please explain how? Or do you mean this more accurate version:
"I've heard that reasoning but this infers that the fluid was already due for flushing."

Nothing wrong with this approach at all. However, if your driving habits, mileage and maintenance practices point to a fluid renewal more or less in conjunction with pad changes, no harm done in accomplishing both at once, either. I know it will come as a shock and surprise, but there are folks who'll replace pads and even rotors on their own, and never once have the thought cross their mind that it may be a fine idea to renew the brake fluid once in awhile! For these, I think the bleeder method is preferable as it relieves them of the smallest bit of fluid that has been exposed to the highest heat and most temperature cycles. Maybe a small nit to pick, but in the long haul, probably goodness.

 

Good Lord, that started a bushfire.

My training, and LONG before ABS appeared, was to NEVER push old contaminated fluid back into the system.

ABS poses even more issues, and pushing fluid back can introduce a particle of "junk" into that valve body arrangement, and that is going to cost ya.

Brake fluid should be changed every 2 years Max, its printed on the bottles.

I have always done the "crack" way, and then bleed all 4 corners. I also use a different colour fluid each time, then teh OLD eyes can see the New appear and then I move on to the next wheel.

In all my Jags since 1968 I have only ever replaced 1 Master cylinder, and I firmly believe my annual brake fluid flushing is in my favour.

I will NEVER criticise anyones procedure, its their car and wallet.

 

Tomayto, tomahto.

 

OK, dont panic, solves very little.

Bleed the brakes, WELL. take your time.

On my X200 cars, both of them, I worked the handbrake numerous times after the rear pads were installed. This "appeared" to reset the handbrake system. However, I never use the hand brake, so it was just my idea of resetting the threaded piston arrangement, good or bad, dunno.

I also agree, that maybe a rotor is not seated correctly, and it dont take much to get that wrong.

I have not messed with the handbrake cable when doing the rears on the cars. the rears are fiddly, and the angle of the dangle is important.

My Black car had the RHR tight to wind back, but it went home eventually, and the car is fine.

I think a quiet revisit, careful looking at what was done, will find the culprit/s.

 

I'm now in the mood for some Sunday Semantics© and believe my original statement using the term 'overdue' is correct.

A maintenance task should be accomplished before a problem occurs. Brake fluid is has been determined to be 'due' ever two years. The old fluid at that point has not yet caused a problem.

If the fluid is not changed at this interval the task is 'overdue' and may result in a problem.

If the bleed nipple crowd believes that pushing <2 year old fluid backwards will cause a problem, the two year interval is incorrect.

Back to important stuff

 

Not so fast, Kimosabe!
"Tomayto!" - if the bleeder's pad change (unfortunate twist-of-phrase there, for sure!) occurs exactly two years from when fluid last renewed; "due" still applies. Further into your semantics, since you hold that maintenance tasks should be accomplished "before" a problem occurs then extend that definition to mean "may cause a problem" and thus said maintenance has become overdue, then I may rightly argue that if the bleeder changes pads anytime BEFORE the two year interval, the fluid ported overboard during the procedure is, at worst, "due" for renewal. More likely, "not yet due."

Interesting you've copyrighted "Sunday Semantics!" that is simply greatness. While I'm not a cunning enough linguist to determine if this is "semantics" or grammar, I nonetheless find fault with it as well:
I believe "every" is indicated, no?

 

A spelling error is not the same as a grammatical error. I am guilty of committing the former. A spelling error not caught by a computer's spell check function is technically called a Kerouism, but that's a story for another day.

If the pad change and fluid change task happen to be due on the same day, then there is no harm done by forcing the old fluid back into the system by changing the pads first. The fluid is still in serviceable condition, if we are to accept the 2 year time interval as being acceptable.

Debating whether the fluid or the pads be changed first is like arguing whether the bacon goes on top of the cheese on a hamburger or vice versa

 

I saw what you did there!

Back to the thoroughly off-topic grammar discussion, just remember the most important rule I was taught:

A preposition is nothing to end a sentence with.


Reluctantly dragging the conversation back on topic:

For the dragging caliper, I've had several instances where a simple pad change turned into a caliper replacement. I think internal corrosion was the culprit. When you retract a caliper to fit new pads, the piston is now riding on area that hasn't seen any motion for a long time. If there's any internal corrosion, that's where it's going to be, not where the piston had recently been operating.

Now if dealing with a high-usage situation like a NYC taxicab, with lots of miles and heavy brake usage/abuse, there isn't much time for internal corrosion to build up before the pads need to be changed. Compare with our personal vehicles, often babied and not racking up lots of miles, either. On my car, for example, it's been over 8 years since I replaced the pads, and there is still plenty of life left on them. Even though I've flushed the brake fluid a couple of times since replacing the pads, I fully expect the calipers may bind when retracted once the pads are finally due for replacement down the road.

It's still possible, in the OP's situation, that there's something amiss with the parking brake system. But once that is ruled out, if the car fits the light usage profile, the pistons may now be riding where corrosion is likely to collect.

 

Oh the horrors! Have you no respect for the food rules passed down from our ancestors? Cheese on top of the bacon is so wrong, I don't even know where to start...

And by the way, it's no longer a hamburger once you've added cheese, even if doing it the clearly wrong way. It's now a cheeseburger. I think we can all agree on that. Let's all join in on a round of Kumbaya.

 

From this, we infer that your spell-checker flagged it and you disregarded the caution? Or will you cop to committing a Kerouism? I might ask, in what way or manner have you misspelled the word, "ever?" but nah, let us also leave that for another day.

Nonetheless, well-played all 'round, even so well off-topic. Sorry OP.

 

I'm a bleeder, my pet theory is that as my pads wear, I obviously top off my fluid as the pistons extend and the level drops, if I just push it back it's possible to have too much fluid in the reservoir, better to bleed it off and check the level when finished.
I've also heard both sides of the pushing fluid back argument, I'm not sure who's right but if it's not pushed back there is no chance of a problem is there?

 

I had my rear pads reversed which caused dragging and overheating before.

 

A Kerouism (rhymes with but is the opposite of 'heroism', now that I think of it) is named after a former coworker who had been threatened with termination for consistently and defiantly not using a spell checker prior to sending written communications to customers. His subsequent downfall was simply accepting the first suggested word offered by the spell checker and not proof reading things before hitting 'send'. A psell shecker cannot help if the writer has chosen the wrong word but spelled it correctly.

The same as spell checker may not know whether the writer means 'breaks' vs. 'brakes' as we see here so often it also cannot really help with homophones. There, their and they're are frequently interchanged.

The final straw was when this poor fellow sent out a message (in the boss's name) announcing 'weir a bout to lunch a plot program' instead of 'we're about to launch a pilot program'.

As for me, I did type 'ever' instead of 'every' but failed to proof read. I blame the single malt.

 

Some entertaining and useful responses. Would it be of use to back out the caliper piston then maybe recompress in order to help loosen it up. The pads I pulled out were actually in decent shape with maybe another 15-20k of life left in them. maybe try putting them back in? I'll recheck my work nonetheless. Especially on the front. I hope my new rotors aren't warped.
