Damage Brake caliper

[Gendut]

thanks bro Gendut & Aeromania for your advice.

 

will convert to stock & slowly working to another or new brake kits.

 

 

to you.

 

You will find it a pinch to replace those calipers but as time goes by, please remind yourself that you have not met with an accident because of your actions now.

If you are a workshop owners, for more than 2 decades, you will realise that many specialty wrenches you purchased ( if they are still around) may not be of much use in our new modern cars where the bolt and nuts are locate in very tight spacing that left very little wrench space. It will be foolish to use over physical size wrenches to service the modern cars.

In the good old days, many equipment maintenance fitters will carry one adjust spanner, one 1lb hammer and one long flate screwdriver. Today your cars comes not only hex bolt and nuts, philip and flat screws but with Torx, Spine, five sided tampered screw etc etc.

Because the factory ONLY wants Agents to do the repair,i once encounter a special spanner,its brand "KTC",is a well known in the market,when i go to this "KTC" agent,they cannot find this spanner,so they ask the "KTC" Japan,the answer is that spanner only made special for Toyota,don't sell it outside.

Tools to Toyota Dealers are normally sold via Banzai who in turns source them.KTC is one of thier supplier.

From the photo and yr description leading to brake fluid leak , my conclusion is the brake female fitting threads are damaged due to cross threads. Most likely is due to inexperience mechanics trying to fit the flared male fitting to the thread hole without success and end up using force resulting in cross threads.

The thread were pull off when the brake fluid built-up hydraulic pressure because of poor thread contacts ( cross thread).

Very poor mechanical skill and definelty using improper tools.

If this poor workmanship work does result in a road accident, in countries like US Uk or Aust, the insurance company will defintely arrow the shop owner.But here cars owners bear the cost to provide training for those grease monkeys !!

 

This is where honest and good ethical mechanics are getting lesser and rare in Singapore as the days go by. Haiz.

thanks bro ken

tik ur words make sense, will be more careful when dealing with 2nd hand stuffs

 

cheers

 

I think we all learn from experience as we grow as drivers.

 

I will never get 2nd hand brakes, rims and tyres as I do not know the actual conditions of these items in particular, we have no idea of the driving style of previous drivers/owners and the history of what was going to be sold to us.

 

With that in mind, one will definitely spend the money for new brakes, rims and tyres as far as our lives and safety are concerned.

though i still have some questions in mind, hopefully some bros here can enlighten/share with me.

 

1) normally, wad's the life span for the brake kits like tis?

2) wad's the interval range to service/overhaul the caliper?

3) does tis caliper produce metal squeal sounds during low speed braking & ESPECIALLY reverse parking braking? during reversing, the sounds is unbearable, is tis normal?

 

many thanks in advance

 

For (1), I have no experience with such brake kits and so I cannot comment.

 

For (2), I have yet to service or overhaul my brake caliper since I had driven my car for more than 103k km in mileage.

 

For (3), it is definitely abnormal. Please go to a workshop and have it rectified as soon as possible.

Defensive practice is good, but no guarantee that you will not encounter situations where you depend on effective emergency braking to save yourself for being hurt. Get the best braking systems for yourself. It may cost you a bomb, but you are worthy of more than that.

 

Not just brake systems. The rubbers play an important role as well.

thank you all bros who have input your valuable advice to me.

 

learnt my lesson of gettin 2nd hand stuffs, will be more careful.

 

currently on stock & gettin a brand new replacment soon.

 

while we r still on replacement, i was wondering if it is alright juz to replace 1 caliper instead of both which only 1 caliper is affected.

 

any bros can enlighten me on this?

 

many thanks in advance

Which/What rubbers do you meant?

Which/What rubbers do you meant?

 

Grippy tyres.

[Good-Carbuyer]

Grippy tyres.

I thought that is part of the braking system?

Well, you can interpret it that way but some people prefer to isolate them separately.

Can braking system really works without tire for cars? I mean without crashing or sideswipe something...
